Why Choose the Mersen W300606 Protistor® High-Speed Fuse?
The Mersen W300606 (PC70UD13C250EF) is a Protistor® Size 70 high-speed square body semiconductor fuse engineered to protect modern power electronic equipment against destructive short-circuit currents. Designed for demanding industrial applications, it delivers ultra-fast fault interruption and excellent current limitation to protect valuable semiconductor devices.
Designed specifically for protecting diodes, thyristors, GTOs and IGBT devices, the W300606 features pure silver fuse elements embedded in solidified sand to achieve low let-through energy (I²t) and high interrupting performance. Silver-plated contact surfaces and non-magnetic hardware provide dependable long-term operation in critical industrial environments.
The W300606 is suitable for OEM equipment, maintenance and replacement applications where identical electrical ratings and mounting arrangements are required. Always verify the complete part number and electrical characteristics before installation.
