Mersen PC92UH15C400TF Protistor High-Speed Fuse, 400A 1500VAC, Size 92 aR, Square Body Flush End with Striker (J076162)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 400A 1500VAC

The Mersen PC92UH15C400TF (Part Number: J076162) is an ultra-fast acting fuse engineered for the protection of high-power semiconductor devices. Part of the specialized Protistor® PSC series, this fuse is optimized for 1500VAC systems, making it an ideal choice for large-scale power conversion equipment such as rectifiers, inverters, and motor drives. With a 400A current rating and a Size 92 square body design, it provides superior protection for SCRs, thyristors, and IGBTs in demanding industrial environments.

Constructed with high-grade ceramic and pure silver elements, the PC92UH15C400TF provides a high breaking capacity of 200kA. The flush-end configuration allows for low-inductance bolted connections, ensuring minimal power loss and maximum electrical efficiency. The inclusion of a mechanical striker provides immediate visual indication of fuse operation and allows for the integration of optional microswitches for remote signaling and automated system shutdowns.

Key Features:

• Ultra-Fast Performance: Classified under the aR utilization category for high-speed interrupt performance against short-circuits in semiconductor circuits.
• Extreme Voltage Rating: Designed specifically for high-isolation requirements in 1500VAC applications.
• Optimized I²t Values: Engineered to minimize energy let-through, significantly reducing the risk of damage to sensitive downstream electronic components.
• Robust Construction: Features a thermal-shock resistant ceramic body and silver-plated contact surfaces for long-term reliability.
• Integrated Monitoring: Equipped with a built-in striker (Type TF) for local status indication and remote fault monitoring compatibility.
