The Mersen Q300601 (PC70UD13C80EF) is a premium square body semiconductor protection fuse engineered to provide ultra-fast protection for sensitive power electronic equipment. Part of the proven Mersen Protistor® Size 70 series, this aR high-speed fuse is designed to protect diodes, thyristors, GTOs and IGBTs used in industrial power conversion systems.
Designed for demanding industrial applications, the Q300601 delivers outstanding current limitation and low let-through energy to minimise damage during short-circuit faults. Its solid ceramic body, silver-plated contacts and integrated striker indicator ensure dependable performance and long service life in mission-critical electrical installations.
With a rated current of 80 A and a 1250 V AC IEC / 1300 V AC UL voltage rating, the Mersen Q300601 is ideally suited for protecting industrial drives, UPS systems, renewable energy equipment, power converters and other semiconductor-based applications.
High-speed semiconductor fuses are specifically engineered to interrupt fault currents before sensitive electronic components can be damaged. Their ultra-fast response and low let-through energy provide significantly greater protection than conventional industrial fuses, helping to maximise equipment reliability and minimise downtime.
The Protistor® range is trusted worldwide for industrial automation, variable speed drives, UPS systems, renewable energy installations and power conversion equipment where reliable semiconductor protection is essential.
