High Voltage DC Fuse 630 mo 1


The High Voltage DC Fuse ( Cylindrical Fuse) is an essential component in solar energy and storage systems. Its primary function is to provide protection by interrupting the current flow in the event of a fault, such as an overcurrent or short circuit. This prevents damage to the system and ensures safe operation. The High Voltage DC Fuse is used in both photovoltaic (PV) solar systems and energy storage systems, where high DC voltage and current levels are present. Its reliability, durability, and high interrupting capacity make it an ideal solution for these applications.
