The Mersen FR10GR69V16 (Item No. D1014579) is a premium Protistor® high-speed cylindrical semiconductor fuse designed to provide full-range (gR) protection for sensitive semiconductor devices. Engineered specifically for power electronic applications, it safeguards inverters, UPS systems, variable speed drives and other semiconductor equipment against overloads and short-circuit faults while minimising damage to expensive components.
Manufactured to comply with IEC 60269-4, this international 10 × 38 mm cylindrical fuse combines low I²t characteristics with exceptional current-limiting performance, ensuring rapid fault clearance and improved protection for IGBTs, thyristors, SCRs, diodes and rectifiers.
Rated at 16 A and 690 V AC, the FR10GR69V16 delivers dependable protection in compact industrial electrical installations where reliable semiconductor protection is critical.
The FR10GR69V16 is engineered to rapidly clear fault currents before excessive thermal energy reaches sensitive semiconductor components. Its low let-through energy helps maximise equipment life while reducing maintenance costs and production downtime.
Mersen Protistor® fuses are widely used throughout industrial automation, renewable energy systems, motor drives, UPS installations and power conversion equipment where dependable semiconductor protection is essential.
