Mersen PC292UH15C11CTF Protistor High-Speed Fuse, 1100A 1500VAC, Size 2x92 aR, Square Body Flush End with Striker (X076245)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 1100A 1500VAC

The Mersen PC292UH15C11CTF (Reference Number: X076245) is an ultra-fast acting fuse belonging to the high-performance Protistor® PSC Square Body series. Engineered for the protection of high-power semiconductor devices, this Size 2x92 dual-body fuse is rated for a continuous current of 1100A and a voltage of 1500VAC. It is specifically designed to meet the extreme demands of large-scale electrical infrastructure, including industrial rectifiers, utility-scale power converters, wind turbine inverters, and heavy traction power systems.

Classified under the "aR" utilization category, this fuse provides specialized short-circuit protection for power electronics such as diodes, thyristors, and IGBT modules. It features extremely low I²t let-through values, ensuring that peak fault energy is cleared instantly to prevent catastrophic damage to sensitive downstream components. The Type C Flush End design with internal metric threads provides a low-inductance connection and exceptional thermal contact with busbars. This unit includes an integrated mechanical Type TF striker, enabling clear local trip indication and compatibility with auxiliary microswitches for remote system monitoring.

Key Features:

• Ultra-Fast Semiconductor Protection: Optimized aR characteristics for exceptionally rapid fault clearing and minimal energy let-through.
• Maximum Current Density: 1100A rating provides reliable performance in high-load industrial power applications.
• High Voltage Range: Rated at 1500VAC, ideal for high-voltage energy conversion and distribution systems.
• Robust Size 2x92 Geometry: Dual-body construction ensures superior heat dissipation and mechanical durability under heavy duty cycles.
• Exceptional Breaking Capacity: Certified to safely interrupt short-circuit currents up to 150kA at 1500VAC.
• System Integration: Built-in TF striker facilitates immediate visual fault detection and simplifies remote monitoring via auxiliary contacts.
