Why Choose the Mersen G076412 Protistor® High-Speed Fuse?

The Mersen G076412 is a Protistor® NH Size 00 high-speed semiconductor fuse designed to provide ultra-fast protection for sensitive power electronic equipment. Catalogued as DN00UD10C40L, this aR class fuse is rated at 40 A and 1000 V AC (IEC), making it ideal for protecting IGBTs, thyristors, diodes and rectifiers from damaging short-circuit currents.

Engineered for demanding industrial applications, the G076412 features an NH Size 00 square-body construction with DIN 80 silver-plated blade terminals and an integrated striker indicator for visual and remote fuse status indication. Pure silver fuse elements embedded in solidified sand provide exceptional current-limiting performance and low I²t values, helping minimise damage to valuable semiconductor devices.

With a 120 kA breaking capacity, this Protistor® fuse is widely used in industrial motor drives, power converters, UPS systems, renewable energy equipment and other semiconductor-based applications where rapid fault clearance is essential.
