The Mersen P075913 is a high-performance Protistor® high-speed semiconductor fuse-link designed to provide dependable protection for sensitive power electronic equipment. Its extremely fast operating characteristics and high breaking capacity make it suitable for demanding industrial systems containing diodes, thyristors, IGBTs and other semiconductor devices.
Featuring a gR full-range operating class, the P075913 protects semiconductor circuits against both overload and short-circuit currents. Its current-limiting performance helps reduce peak fault current and let-through energy, limiting electrical, thermal and mechanical stress within valuable power conversion equipment.
With a rated current of 90 A and an IEC rated voltage of 690 V AC, the Mersen P075913 is suitable for variable frequency drives, industrial rectifiers, inverters, UPS systems and power converters. Its 2 × 17 × 49 mm British Standard fuse-link format, bolted connections and integrated striker support secure installation and convenient fuse-operation indication.
The Mersen P075913 is engineered to interrupt dangerous currents before excessive energy can damage sensitive semiconductor components. Its rapid operation and current-limiting characteristics help reduce fault energy within power electronic assemblies, improving equipment reliability and limiting the risk of costly component failure.
The gR operating characteristic provides full-range protection against both overload and short-circuit currents. This offers improved safety and enables selective coordination with other correctly selected fuses within an industrial electrical distribution system.
