The Mersen F300362 is a Protistor® Size 33 square body high-speed semiconductor fuse engineered to provide ultra-fast protection for sensitive power semiconductor devices operating in industrial power conversion equipment. Designed for demanding applications, it delivers exceptional current limitation, helping to minimise damage caused by short-circuit faults whilst maximising system reliability and uptime.
This fuse belongs to the Protistor® Size 33 aR series and is specifically designed for protecting IGBTs, SCRs, thyristors, diodes and other semiconductor devices. It features precision fuse elements embedded in silica sand to achieve very low let-through energy and rapid fault clearance.
Rated at 630 A with a 690 V AC operating voltage, the F300362 features TDF bolted terminals with an integrated striker (Percuteur), making it ideal for industrial drives, UPS systems, converters, rectifiers and renewable energy equipment.
Protistor® semiconductor fuses are engineered specifically to protect modern power electronics where extremely fast fault interruption is essential. Their low let-through energy significantly reduces thermal and mechanical stress on semiconductor devices, helping extend equipment life and reduce downtime.
The Mersen F300362 is widely used by OEMs, panel builders and maintenance engineers in industrial automation, renewable energy, motor drives and power conversion systems requiring dependable semiconductor protection.
