£144.86
The Mersen J076414, catalogue number DN00UD10C63L, is a Protistor® NH size 00 square body high-speed semiconductor fuse engineered to provide advanced protection for power semiconductor devices used in industrial power conversion equipment. It features an aR ultra-fast operating characteristic, DIN 80 blade contacts and an integrated striker indicator for rapid fault indication.
Rated at 63 A and 1000 V AC (IEC), the J076414 has been designed to minimise let-through energy (I²t), helping to protect sensitive components such as IGBTs, thyristors and diodes from damaging short-circuit currents. Its ceramic body, silver-plated contacts and high interrupting capacity make it suitable for demanding industrial environments.
As part of the Mersen Protistor® semiconductor protection range, this fuse is ideal for variable frequency drives, industrial inverters, UPS systems, rectifiers, renewable energy equipment and other power electronic applications requiring dependable semiconductor protection.
Protistor® semiconductor fuses are engineered to interrupt extremely high fault currents before excessive thermal energy reaches sensitive semiconductor devices. Their low I²t performance helps maximise equipment reliability while reducing maintenance costs and production downtime.
The J076414 is particularly suitable for protecting converters, drives, UPS systems, renewable energy equipment and other industrial power electronic systems operating at up to 1000 V AC.
