Mersen PC92UK15C400TF Protistor High-Speed Fuse, 400A 1500VAC, Size 92 aR, Square Body Flush End with Striker (J076415)

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

The Mersen PC92UK15C400TF (Reference Number: J076415) is a high-performance ultra-fast-acting fuse specifically engineered for the protection of power semiconductor devices. As part of the prestigious Protistor® PSC series, it is designed for 1500VAC applications, providing reliable protection for power rectifiers, high-voltage inverters, and large-scale industrial motor drives. Featuring a 400A current rating and a Size 92 square body, it is optimized to protect sensitive components such as SCRs, thyristors, and IGBTs.

Constructed with premium materials including a high-grade ceramic body and pure silver elements, the PC92UK15C400TF ensures high breaking capacity and exceptional cycling capability. The UK-style flush-end design facilitates low-inductance mounting, which is critical for reducing voltage spikes during fault clearance. This model includes a built-in mechanical striker (Type TF), enabling local visual indication and providing the option to trigger remote microswitches for circuit monitoring.

Key Features:

• Ultra-Fast Acting Performance: Globally recognized aR utilization category ensures rapid interruption of short-circuit currents.
• High Voltage Rating: Purpose-built for high-power conversion systems operating at up to 1500VAC.
• Low I²t Let-Through: Minimizes thermal impact on downstream electronics during a fault event.
• Enhanced Reliability: Silver-plated contact surfaces and thermal-shock resistant housing for long-term service in harsh industrial environments.
• Integrated Fault Indication: Features the TF-type striker for immediate status monitoring and remote signaling compatibility.
