Mersen PC293UK15C900TF Protistor High-Speed Fuse, 900A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker (A076248)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 900A 1500VAC

The Mersen PC293UK15C900TF (Reference Number: A076248) is a high-capacity ultra-fast-acting fuse from the specialized Protistor® PSC Square Body series. Engineering specifically for the protection of high-power semiconductor devices, this Size 2x93 dual-body fuse is rated for 900A at 1500VAC. It serves as a critical protection component for heavy-duty industrial power electronics, including large-scale rectifiers, high-performance DC drives, static transfer switches, and utility-scale solar/wind inverters.

Adhering to the "aR" utilization category, this fuse offers partial-range short-circuit protection specifically for circuits containing diodes, thyristors, and IGBT modules. It features extremely low I²t let-through and peak current values, which are essential for preventing thermal damage to semiconductors during fault conditions. The Type C Flush End design utilizes internal metric threads to ensure a high-pressure, low-resistance mechanical connection to power busbars. Integrated with a Type TF mechanical striker, the fuse provides immediate local visual status of its operation and is compatible with microswitches for remote signaling within automated monitoring systems.

Key Features:

• Ultra-Fast Semiconductor Protection: Optimized "aR" characteristic for rapid fault interruption and minimal heat dissipation during clearing.
• High Power Density: 900A continuous current rating, providing reliable service in high-current industrial environments.
• 1500VAC Rated: Specifically designed for high-voltage energy conversion and large power distribution networks.
• Dual-Body Size 2x93: Robust square body configuration ensures excellent mechanical stability and superior thermal performance.
• High Breaking Capacity: Engineered to safely manage and interrupt short-circuit currents up to 150kA.
• Advanced Monitoring: Equipped with a TF mechanical striker for quick fault identification and optional remote system integration.
