Why Choose the Mersen NH000UD69V100PV High-Speed Semiconductor Fuse?
The Mersen NH000UD69V100PV is a Protistor® NH Size 000 high-speed semiconductor fuse engineered to provide exceptional short-circuit protection for modern power electronic equipment. Designed with an ultra-fast aR operating characteristic, it delivers reliable protection for sensitive semiconductor devices including IGBTs, thyristors, diodes, GTOs and rectifier assemblies.
With a rated current of 100 A, 690 V AC (IEC) and 700 V AC (UL) voltage ratings, the NH000UD69V100PV is suitable for industrial drives, inverters, UPS systems, converters and other demanding power electronic applications. Manufactured in the internationally recognised NH Size 000 format, it offers compatibility with DIN 43620 NH fuse bases and switch disconnectors.
Constructed using pure silver fuse elements embedded in high-grade quartz sand with silver-plated contacts, the Protistor® fuse provides low let-through energy, helping to minimise thermal stress during fault conditions while maximising equipment protection and reliability. A double visual indicator enables rapid fuse status identification and can be used with an optional microswitch for remote indication.
