Why Choose the Mersen J076414 Protistor® High-Speed Fuse?

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.
