MERSEN FUSE 6,6 URC 000 BS88Z P 280 N330154

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.

Rapid Protection for Industrial Power Electronics

The Mersen N330154 is engineered to interrupt high fault currents before excessive energy can reach sensitive semiconductor devices. Its ultra-fast operation helps minimise peak current and total let-through energy, reducing the likelihood of damage to power modules and associated electrical equipment.

High-speed semiconductor fuses are particularly important in power conversion systems because conventional industrial fuses may not operate quickly enough to protect sensitive electronic components. The N330154 provides the rapid response required for critical industrial drive, rectifier and inverter applications.

Typical Applications

• Variable frequency drives and motor-control systems.
• Industrial power converters and rectifiers.
• Inverters and renewable-energy conversion equipment.
• Uninterruptible power supply systems.
• Industrial battery chargers and DC power supplies.
• Semiconductor-controlled machinery and automation systems.
