Why Choose the Mersen P082376 High-Speed Semiconductor Fuse?
The Mersen P082376 is an ultra-rapid Protistor® high-speed semiconductor fuse-link designed to protect sensitive power electronic equipment against damaging short-circuit currents. Its fast operating characteristics and effective current limitation make it suitable for demanding industrial systems containing diodes, thyristors, IGBTs and other semiconductor devices.
Identified by the catalogue designation 2,5 URGH 236 T 300 and alternative SKU BS236UH25V300T, the P082376 features an aR partial-range operating class developed specifically for semiconductor protection. Its rapid response helps restrict peak fault current and let-through energy, reducing electrical, thermal and mechanical stress within power conversion equipment.
With a rated current of 300 A and a rated voltage of 250 V AC, the Mersen P082376 is suitable for industrial drives, rectifiers, converters, inverters and power supplies. Its 2 × 36 × 27 mm British Standard fuse-link format, angled bolted terminals and integrated striker support secure installation and convenient fuse-operation indication.

Rapid Protection for High-Current Power Electronics
The Mersen P082376 is engineered to interrupt dangerous fault currents before excessive energy can reach sensitive semiconductor components. Its ultra-rapid operation helps limit peak current and total let-through energy, reducing the likelihood of damage to power modules and associated electrical equipment.
As an aR-class fuse, the P082376 provides partial-range protection specifically against semiconductor short-circuit currents. Suitable supplementary overload protection should be incorporated where complete protection against both overload and short-circuit conditions is required.
Typical Applications
- Variable frequency drives and industrial motor controllers.
- High-current rectifiers and power converters.
- Industrial inverters and power conversion systems.
- Uninterruptible power supply equipment.
- Battery chargers and DC power supplies.
- Semiconductor-controlled machinery and automation systems.
