WESTCODE 125UR2S0630B Ultra-Rapid Semiconductor Fuse, 630A 1250V, Bolted - Pack of 3

WESTCODE 125UR2S0630B Ultra-Rapid Semiconductor Fuse, 630A 1250V (Pack of 3)

The WESTCODE 125UR2S0630B is a high-performance ultra-rapid semiconductor fuse designed to provide essential overcurrent protection for critical power semiconductor devices in high-power and high-voltage applications. Rated for a formidable 630 amps and 1250 volts, this gR-characteristic fuse is engineered to clear fault currents with extreme speed, effectively safeguarding sensitive and often costly components such as IGBTs, thyristors, diodes, and other power rectifiers or inverters from potential damage due to short circuits and overloads.

As part of the WESTCODE product line, now integrated with Littelfuse, this fuse embodies a legacy of robust engineering and reliability. Its high breaking capacity ensures safe interruption of even severe fault currents, making it an indispensable component for demanding industrial power systems. Typical applications include industrial motor drives, high-power UPS systems, traction and transportation systems, renewable energy converters, and large-scale power conversion equipment where maximum uptime and component protection are paramount. This bulk pack of three fuses ensures you have sufficient spares for maintenance, repair, or small-scale production requirements.
