Why Choose the Mersen G301835 Protistor® High-Speed Fuse?
The Mersen G301835 (PC71UD13C200PA) is a premium square body high-speed semiconductor fuse from the Protistor® Size 71 aR series, engineered to provide exceptional short-circuit protection for modern power electronic equipment. Designed specifically for semiconductor applications, it protects sensitive devices such as IGBTs, thyristors and diodes by rapidly interrupting fault currents while minimising let-through energy.
Featuring an aR ultra-fast operating characteristic, pure silver fuse elements embedded in solidified sand, silver-plated contact surfaces and non-magnetic hardware, the G301835 delivers excellent current limitation, low I²t values and high interrupting performance. The integrated striker indicator also allows convenient fuse status indication and optional remote signalling when used with compatible accessories.
Rated at 200 A with a 1250 V AC IEC / 1300 V AC UL voltage rating, this fuse is ideally suited for high-voltage power conversion equipment including industrial drives, UPS systems, renewable energy inverters and other demanding semiconductor protection applications.
