High-speed Protistor® NH2GS69V250PV fuse rated at 250A for 690VAC IEC and 700VAC UL with double visual indicator and NH size 2 square body for robust industrial and photovoltaic protection.
£74.54
The Mersen NH2GS69V250PV is an industrial NH Size 2 high-speed fuse designed to provide dependable protection for semiconductor equipment, power conversion systems and associated electrical circuits. Manufactured by Mersen, it combines fast fault interruption with full-range overcurrent protection for demanding industrial installations.
Featuring a gS utilisation category, the NH2GS69V250PV is designed to protect semiconductor devices against both overload and short-circuit conditions. This makes it suitable for applications where coordinated protection of sensitive power electronics and connected conductors is required.
With a rated current of 250 A and a rated operating voltage of 690 V AC, the NH2GS69V250PV is suitable for variable frequency drives, industrial converters, motor-control equipment and power distribution assemblies. Its standard NH blade format supports secure installation in compatible NH Size 2 fuse bases and switch-fuse units.
High-speed fuses are engineered to interrupt fault currents before excessive electrical and thermal energy can damage sensitive semiconductor components. Their low I²t characteristics help reduce stress on diodes, thyristors, IGBTs and other power electronic devices.
Unlike partial-range semiconductor fuses, a gS fuse provides full-range protection against both overload and short-circuit currents. This can simplify protection coordination in drives, converters and industrial power systems while helping improve equipment reliability and reduce unplanned downtime.
