The Mersen N300001, catalogue number PC31UD69V200TF, is a premium Protistor® Size 31 square body high-speed semiconductor fuse engineered to provide ultra-fast protection for modern power electronic equipment. Designed specifically for semiconductor applications, it protects IGBTs, thyristors, diodes and other sensitive semiconductor devices from damaging short-circuit faults.
Featuring a 200 A current rating, 690 V AC IEC / 700 V AC UL voltage rating and an aR operating class, the N300001 delivers excellent current-limiting performance with low let-through energy. Its compact square body construction makes it ideal for industrial drives, converters, UPS systems and renewable energy applications.
The fuse incorporates a Size 31 square body design with flush-end metric threaded terminals, silver-plated contacts and an integrated striker indicator, allowing simple installation and optional remote fuse indication using compatible microswitches.
Protistor® semiconductor fuses are engineered to interrupt high fault currents before damage occurs to expensive semiconductor devices. Their ultra-fast operating characteristics reduce thermal stress, improve system reliability and minimise downtime in demanding industrial applications.
The Mersen N300001 is ideally suited to industrial motor drives, power converters, UPS systems, renewable energy equipment and OEM electrical panels requiring dependable semiconductor protection.
