The Mersen C301302 is a Protistor® Size 73 high-speed semiconductor fuse designed to provide exceptional protection for high-power semiconductor equipment. Engineered for demanding industrial applications, it delivers ultra-fast fault interruption to protect IGBTs, thyristors, SCRs, rectifier diodes and other power semiconductor devices against damaging short-circuit currents. It is part of the Mersen Protistor® Size 73 aR series, developed specifically for modern power conversion equipment.
The fuse incorporates precision die-cut fuse elements embedded in solidified sand to achieve low let-through energy and excellent current-limiting performance. Silver-plated contact surfaces and non-magnetic hardware enhance long-term reliability, while the integrated striker indicator can operate an optional microswitch for remote indication.
Rated at 1800 A with a 600 V AC IEC / 650 V AC UL voltage rating and a 200 kA AC breaking capacity, the Mersen C301302 is ideally suited to heavy-duty industrial drives, renewable energy systems, UPS installations and large power conversion equipment.
Protistor® Size 73 fuses are engineered to provide state-of-the-art protection for high-power semiconductor devices operating in demanding industrial environments. Their ultra-fast current-limiting characteristics significantly reduce fault energy before expensive electronic components can be damaged, improving equipment reliability while minimising downtime.
The Mersen C301302 is ideal for protecting industrial motor drives, rectifiers, inverters, renewable energy converters, UPS installations and other high-power semiconductor applications requiring dependable short-circuit protection.
