2026 China Top 7 Load Center Manufacturers

A load center — also called a panelboard or breaker box — is the point where incoming electrical service splits into individually protected branch circuits. This guide is scoped to Chinese manufacturers that meet two conditions: the company maintains its own independent official website (not only a third-party B2B storefront), and a load center — or a directly equivalent North American-style panel board — can actually be found in that website’s product catalog. Several well-known Chinese low-voltage electrical groups were excluded from this list for that second reason: their catalogs cover switchgear, motor control, or general distribution boxes, but a dedicated load center product page could not be verified on their own sites.

One naming note worth flagging directly: the domain chnt.com is not operated by CHINT Group (the large conglomerate at chintglobal.com). It belongs to a separate, unrelated Yueqing manufacturer — YUANKY / Wenzhou Hawai Electron & Electric — and is identified as such below to avoid confusion between the two similarly abbreviated names.

Rather than padding the list to a round number, it includes every manufacturer that could be verified against both conditions above at the time of research. Companies are ordered by overall scale (factory size, employee count, years in the category) and certification breadth within the load center segment specifically. Buyers should always confirm current UL/CSA/CB status and lead times directly with each supplier before placing an order.

Quick Reference Table

1. HIITIO

• Founded: 2018, when Hecheng Electric brought in a dedicated R&D team
• Location: Hangzhou, Zhejiang Province, China
• Core products: UL-listed load centers, DC miniature circuit breakers, GFCI breakers, AC disconnect switches, HVDC contactors
• Official website:hiitio.com
• Load center category page:Load Center (UL Listed)
• Featured product:HP Plug-on Neutral Load Centers, Class 1170

HIITIO is a Zhejiang-based manufacturer that grew out of Hecheng Electric’s existing electrical-component manufacturing base, building a dedicated R&D team around protection devices for EV, solar, and energy storage applications before extending that know-how into AC distribution equipment for the HVAC/R and residential construction markets. Within that HVAC/R line, load centers sit alongside GFCI breakers and AC disconnect switches — the same product family a contractor would typically buy together for a panel upgrade. HIITIO reports more than 500 customers across 50-plus countries and operates a 30,000-square-meter manufacturing facility, positioning it as a newer but fast-scaling entrant in the load center segment specifically, rather than a diversified industrial conglomerate that happens to also make panels.

HIITIO’s flagship load center offering is the HP Plug-on Neutral Load Centers, Class 1170, a true plug-on neutral design covering 8 to 60 spaces at 100A, 125A, 150A, 200A, or 225A, available in Main Lugs or Main Breaker configurations. The plug-on neutral bus eliminates pigtail neutral connections at each breaker position, which reduces installation time and lowers the risk of loose neutral connections compared to older screw-and-pigtail designs — a detail that matters more to a licensed electrician doing the wiring than it does on a spec sheet.

Main terminals accept both copper and aluminum conductors (6–2/0 AWG on lower ratings, 4–300 AWG/kcmil on higher ratings), and the line ships in five box sizes (B1–B5) with gray flush front covers and separately ordered HTB/GB ground bar kits, covering residential main and sub-panels, light commercial tenant spaces, multi-family distribution, and panel-upgrade renovation work. HIITIO’s plug-in neutral HSN Series sits alongside the HP Series as a second load center option for buyers who prefer that bus format instead. For buyers comparing certification and enclosure requirements before shortlisting a supplier, HIITIO’s own US Standard Load Center Selection Guide and its comparison of indoor vs. outdoor rainproof load centers are useful background reading.

2. Junon Electrical

• Founded: 1983
• Location: Foshan, Guangdong Province, China
• Core products: Square D-style panel boards, load centers, distribution boards, switches and sockets
• Official website: junonelectrical.com
• Panel board page: Electrical Panel Board Manufacturer

Junon is the longest-established and largest specialist on this list outside of HIITIO, reporting 2,000 to 3,000 employees and an 80,000-square-meter factory footprint across its headquarters and branch facilities in Foshan, Guangdong — a different regional cluster from the Zhejiang-heavy rest of this list. Founded in 1983, the company’s product range centers on panel boards, switches, sockets, and distribution boards, with panel boards built around a structure comparable to familiar Square D-style formats: base box, frame, door, branch switch wiring box, and isolated neutral and ground copper bars.

Junon holds ISO 9001, CCC, CE, CB, SASO, UL, and GCC certifications across its product lines, which is one of the broader certification spreads among the companies profiled here and a relevant checklist for buyers comparing documentation support rather than price alone. The breadth of markets covered by its certifications (SASO for Saudi Arabia, GCC for the Gulf states, UL for North America) suggests a company built for multi-region panel board exports rather than a single home market.

3. YUANKY (Wenzhou Hawai Electron & Electric)

• Founded: 1989
• Location: Yueqing, Zhejiang Province, China
• Core products: Load centers, panel boards, American distribution box & meter, circuit breakers, fuses, contactors
• Official website: chnt.com
• Load center / panel board category: Panel Board

Trading under the brand YUANKY, Wenzhou Hawai Electron & Electric Manufacture Co., Ltd. was started in 1989 and has grown to more than 1,000 employees across a 65,000-square-meter facility in Yueqing, Zhejiang — again, a company that predates most of the newer specialists on this list. Its own site organizes “American Distribution Box & Meter” as a distinct catalog branch from its general distribution box line, and lists named load center products directly, including a D2 series and D4 series “Load Centers & Distribution Board” and a “GEP 3 Phase Panel Board Load Center,” alongside circuit breakers, fuses, contactors and relays, and switch sockets.

YUANKY states certifications including ISO 9001:2008, ISO 14000, and product-level CB, SAA, CE, SEMKO, and UL marks, and reports having sold to more than 100 countries. As with any company whose domain is easy to visually confuse with an unrelated larger group, buyers should double-check the corporate name (Wenzhou Hawai Electron & Electric Manufacture Co., Ltd. / YUANKY) on any quotation or contract before proceeding.

4. Zhejiang Meto Electrical

• Founded: Established in the early-to-mid 2000s (sources vary between 2000 and 2009)
• Location: Liushi Town, Yueqing City, Wenzhou, Zhejiang Province, China
• Core products: Meter sockets, load centers, fuse cutouts, composite insulators, lightning arresters
• Official website: chinameto.com

Zhejiang Meto Electrical is a meter-socket-and-load-center specialist based in Yueqing’s electrical manufacturing cluster, operating under three in-house brands — METO, TRAKOU, and MERTAL. The company states it has exported to more than 40 countries, with a product scope covering metering equipment, load centers and panels, wiring devices, fuse cutouts, and insulators — a narrower, more metering-and-distribution-focused catalog than the broad industrial conglomerates that dominate general China electrical-manufacturer lists. Its certification portfolio is unusually wide for a company of its size: UL (United States), cUL (Canada), CESI (Italy), KEMA (Netherlands), and DEKRA (Germany), alongside domestic testing-institute approvals.

Meto’s load center and meter socket lines are built to ANSI-format specifications rather than IEC formats, meaning the product dimensions, mounting patterns, and breaker compatibility are designed from the outset for North and Central American markets rather than adapted from a European or Chinese domestic base — a meaningful distinction for buyers sourcing specifically for US or Canadian projects.

5. E-abel Electrical Equipments

• Founded: 2011
• Location: Nanhai District, Foshan City, Guangdong Province, China
• Core products: UL-listed load centers (8–42 space), panel boards, meter sockets, electrical enclosures
• Official website: eabel.net
• Load center product page: 8–42 Space UL-Listed Load Center / Panel Board

E-abel Electrical Equipments Inc. was established in 2011 in Foshan and has built a dedicated “Load Center & Panel Board & Meter Socket” product division alongside its broader electrical enclosure business, which now covers more than 60,000 square meters of combined workshop, assembly, and R&D space. The company markets itself specifically around North American power systems — its site includes detailed engineering guidance on single-phase load center specification, main-breaker versus main-lug configuration, and NEMA 1 versus NEMA 3R enclosure selection, indicating a technical sales approach aimed at OEM and prefabricated-building buyers rather than general distributors.

E-abel’s 8–42 space load center line is UL-listed and covers indoor and outdoor (NEMA 3R) configurations, and the company holds UL, CE, SAA (Australia), and ISO 9001 certifications. For buyers assembling private-label or OEM prefab-building electrical packages, E-abel’s published specification framework — covering SCCR, neutral bonding, and breaker-family compatibility — is a useful reference point regardless of which supplier is ultimately selected.

6. Shanghai Newtrend Electric (SNT)

• Founded: Mid-2000s (the company markets “20+ years manufacturing experience” as of 2026)
• Location: Jiading District, Shanghai, China
• Core products: UL-listed load centers, meter bases, distribution boxes, DIN-rail products
• Official website: sntelec.com
• UL-listed load center category page: UL Listed Load Center

Shanghai Newtrend Electric, trading as Newtrend/SNT, is a Shanghai-headquartered exporter that has built its catalog specifically around North American load center formats — including PowerMark, CH, QOD, QOL, and TLS-compatible product lines, plus meter bases and UL-listed load centers under its own SNT brand. Unlike the diversified regional groups excluded from this list, Newtrend positions itself narrowly as a load-center-and-panel specialist for export, OEM, and private-label buyers, which makes its category structure closely comparable to how a North American electrical distributor would organize a catalog.

Newtrend’s UL-listed load center line covers standard flush and surface-mount configurations across common US amperage ratings up to 250A, and the company explicitly markets certification support (UL, CE, CB, RoHS) as part of its OEM and ODM service — a relevant consideration for buyers who need documentation packages alongside the physical product rather than a bare panel with no paper trail.

7. KDM (KDM Fabrication)

• Founded: 2008
• Location: Huishan District, Wuxi, Jiangsu Province, China
• Core products: Load center panels (main breaker and main lug), custom sheet-metal enclosures, NEMA-rated boxes
• Official website: kdmsteel.com
• Load center product page: Load Center Panel Manufacturer

KDM began as a sheet-metal fabrication and custom enclosure business in Wuxi, Jiangsu — outside the Zhejiang/Guangdong electrical clusters that most companies on this list call home — and has since built out a dedicated load center panel product line covering main breaker, main lug, and outdoor rainproof formats aimed at the US remodeling and light-commercial market. Its factory covers more than 8,000 square meters and supports both standard-catalog and custom fabrication work, which reflects its origin as a metal-fabrication house rather than a company that began as an electrical component OEM.

Because KDM’s core competency is precision sheet-metal work (stamping, laser cutting, welding, powder coating) rather than breaker or bus-bar engineering, its load center panels are generally positioned for buyers who value enclosure quality and fabrication precision — a relevant differentiator for private-label or custom-dimension panel projects where a standard catalog item from a pure electrical-component specialist may not fit.

HIITIO HP Series (Class 1170): Technical Snapshot

Since HIITIO leads this list, the table below breaks out the published specifications of its HP Plug-on Neutral Load Centers, Class 1170, so buyers can compare it directly against the load center lines referenced above.

Why HIITIO’s Load Centers Are Worth a Closer Look

If your project needs UL-listed load centers backed by a supplier that also manufactures the complementary protection hardware increasingly paired with residential and light-commercial panels — GFCI breakers, AC disconnect switches, and DC miniature circuit breakers — HIITIO’s HVAC/R product line is built to cover that scope from one factory. The HP Plug-on Neutral Load Centers, Class 1170 cover 8 to 60 spaces across 100–225A ratings in Main Lugs or Main Breaker configurations, with copper or aluminum wire compatibility and five enclosure sizes to match different panel footprints. HIITIO’s broader Load Center (UL Listed) category — which also includes the plug-in neutral HSN Series — sits alongside its HVAC & Refrigeration solution page for buyers assembling a full distribution and protection package rather than a single component. Reach out through HIITIO’s product pages for current lead times, certification documentation, and OEM/ODM terms.

Frequently Asked Questions

What is the difference between a load center and a panelboard?

In practice, the two terms describe the same type of equipment — a distribution point that splits incoming power into individually breaker-protected branch circuits. “Load center” is the more common term in North American residential and light-commercial contexts, while “panelboard” is used more broadly across UL 67, the governing standard, and in commercial/industrial specifications.

Are Chinese-manufactured load centers UL listed?

Some are, and some are not — certification depends on the specific product line and factory, not on the country of manufacture. Every company on this list markets a specific UL or cUL-listed load center or panel board series on its own website, but buyers should request current UL file numbers and verify them independently before ordering.

Why isn’t this a top-10 list?

Because padding a list to a round number with companies that don’t clearly meet the stated criteria — an independent official website with a verifiable load center product on it — would make the comparison less useful, not more. Seven manufacturers met both conditions at the time of research; that is the number listed.

Why does chnt.com not belong to CHINT Group?

Domain names and company abbreviations do not always align with the brand a buyer might expect. chnt.com is registered to a Yueqing manufacturer trading as YUANKY (legal name Wenzhou Hawai Electron & Electric Manufacture Co., Ltd.), an entity separate from CHINT Group, whose official site is chintglobal.com. Buyers should always confirm the legal entity name on any quotation, not just the domain or storefront name.

How should I compare load center manufacturers beyond price?

The most actionable comparison points are: which specific SKUs carry UL, cUL, or CSA certification, what amperage and circuit-count ranges are available, whether the bus bar is aluminum or copper, warranty length, and whether the manufacturer supports OEM/ODM documentation for your target market. Company scale and history matter mainly as a proxy for production consistency and long-term supply reliability.
