WESTCODE 069UR1S0250B Ultra-Rapid Semiconductor Fuse, 250A 690V AC - Pack of 5

WESTCODE 069UR1S0250B Ultra-Rapid Semiconductor Fuse, 250A 690V AC (Pack of 5)

The WESTCODE 069UR1S0250B is an advanced ultra-rapid semiconductor fuse specifically engineered to provide critical overcurrent protection for power semiconductor devices. Rated for 250 amps at 690 volts AC, this fuse is designed to interrupt fault currents extremely quickly, minimizing damage to sensitive and costly components such as diodes, thyristors, IGBTs, and other power rectifiers or inverters. Its ultra-rapid tripping characteristic (gR type) ensures that the fuse clears faults before the let-through energy can exceed the thermal withstand capabilities of the protected semiconductor.

Manufactured by WESTCODE (now part of Littelfuse), a trusted name in power semiconductors and protection, this fuse boasts a high breaking capacity, making it suitable for applications in high-power industrial systems. It is an essential component for ensuring reliability and extending the lifespan of equipment in demanding environments, including industrial motor drives, uninterruptible power supplies (UPS), welding equipment, DC choppers, and various power conversion systems. This pack of five fuses offers a convenient solution for maintenance, repair, and production needs, ensuring you have critical spares on hand to maintain operational continuity.
