£190.49
The Mersen P097464 is a Protistor® high-speed semiconductor fuse-link engineered to provide ultra-fast protection for sensitive power electronic equipment. Also identified by the catalogue number BS236UU69V400T, this fuse is specifically designed to protect semiconductor devices against damaging short-circuit currents while delivering exceptional current-limiting performance.
Featuring an aR partial-range operating class, the P097464 rapidly interrupts fault currents before excessive energy can damage diodes, thyristors, IGBTs, rectifiers and other semiconductor components. Its high breaking capacity and low let-through energy help improve equipment reliability and reduce costly downtime.
With a rated current of 400 A, a rated voltage of 690 V AC and a 2 × 36 × 55 mm British Standard square-body format, the Mersen P097464 is ideal for industrial drives, converters, UPS systems, renewable energy equipment and other demanding power conversion applications. The integrated striker provides convenient fuse-operation indication and supports remote signalling using compatible accessories.
The Mersen P097464 delivers extremely fast interruption of high fault currents before semiconductor junctions can be damaged. Its advanced current-limiting design reduces thermal and mechanical stress on power electronic assemblies, helping maximise equipment availability and extend component life.
As an aR-class fuse, the P097464 provides dedicated protection against semiconductor short-circuit faults. Appropriate overload protection should be provided elsewhere within the electrical system where full-range circuit protection is required.
The robust square-body construction and bolted blade terminals provide dependable electrical connections for demanding industrial environments. The integrated striker can be used with compatible Mersen microswitch accessories to provide remote fuse-status indication for monitoring and maintenance systems.
