Why Choose the Mersen N330154 High-Speed Semiconductor Fuse?
The Mersen N330154 is a high-performance Protistor high-speed semiconductor fuse designed to protect sensitive power electronic equipment against damaging short-circuit currents. Its ultra-rapid operating characteristics and current-limiting construction make it suitable for demanding industrial systems containing diodes, thyristors, IGBTs and other semiconductor devices.
Identified by the catalogue designation 6,6 URC 000 BS88Z P 280, this fuse provides a rated current of 280 A and a rated voltage of 660 V AC. Its fast response helps limit peak fault current and let-through energy, reducing electrical, thermal and mechanical stress within valuable power conversion equipment.
The Mersen N330154 features a compact size 000 BS-style square body with bolted connection terminals and an integrated striker. It is well suited to variable frequency drives, rectifiers, industrial inverters, UPS systems, battery chargers and other applications requiring dependable semiconductor short-circuit protection.
