Why Choose the Mersen A301323 High-Speed Semiconductor Fuse?
The Mersen A301323 (Catalogue No. PC71GB69V200EF) is a Protistor® Size 71 gR square-body high-speed semiconductor fuse designed to provide full-range protection for power semiconductor devices. Rated at 200 A and 690 V AC (IEC), it is engineered for modern power conversion equipment including drives, converters, rectifiers and UPS systems.
Unlike partial-range aR semiconductor fuses, the gR operating class provides protection against both overload and short-circuit faults, making it suitable for applications requiring complete semiconductor protection. The fuse incorporates precision die-cut pure silver elements embedded in solidified quartz sand to achieve rapid fault interruption, low let-through energy and excellent current limitation.
The A301323 features open slot blade terminals (EF) and an integrated striker indicator for remote indication or optional microswitch operation. Silver-plated contact surfaces and non-magnetic hardware ensure reliable long-term performance in demanding industrial environments.

Designed for Complete Semiconductor Protection
The Mersen A301323 has been developed for demanding power electronic installations where both overload and short-circuit protection are required. Its gR characteristic allows complete protection of semiconductor devices without relying solely on additional protective devices, while its low let-through energy significantly reduces thermal stress during fault conditions.
The integrated striker mechanism allows fast visual indication and can operate an optional microswitch for remote monitoring, helping improve maintenance efficiency and equipment availability in industrial installations.
Typical Applications
- Variable frequency drives (VFDs).
- Industrial inverters.
- Power converters.
- Rectifier systems.
- UPS systems.
- Motor drive equipment.
- Renewable energy converters.
- Industrial automation systems.
