Limitations of Traditional High-voltage DC Fuses

High temperature rise and power consumption 2
High temperature rise and power consumption 1

High Temperature Rise and Power Consumption

To ensure the breaking speed of the short circuit, part of the current density of the narrow dia. is designed to be very high, so that the temperature rise and power loss of the fuse at the rated current are relatively high.

Existence of the protection blind sopts

Existence of The Protection Blind Sopts

To reduce the temperature rise and power loss, the fuse usually needs to be used with reduced capacity, and the fuse itself has a minimum reaking current, making the very lower overload current a protection blind spots.

Single protection feature

Single Protection Feature

The protection characteristics of the fuse are determined by the structural size, limited by the rated voltage and current, so it is difficult to flexibly adjust according to the application scenario and protection requirements.

Elevate Your EV Safety with Our Pyro Fuses

low-cost, fast-acting protection switch disconnects the circuit safely, reliably, swiftly, and efficiently, shutting down the power circulation before any short circuit can occur due to vehicle deformation in the case of a crash, accident, or malfunction.
