Mersen PC293UH15C13CTF Protistor High-Speed Fuse, 1300A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 1300A 1500VAC

The Mersen PC293UH15C13CTF is an ultra-fast acting fuse from the world-renowned Protistor® PSC Square Body series. Engineering specifically for the protection of high-power semiconductor devices, this Size 2x93 dual-body fuse is rated for a continuous current of 1300A at 1500VAC. It is an essential component for safeguarding high-performance energy conversion systems, including utility-scale power converters, industrial rectifiers, large UPS units, and traction power substations.

Operating within the "aR" utilization category, this fuse provides specialized partial-range short-circuit protection. It is designed with extremely low I²t (thermal energy let-through) and peak let-through current characteristics, which are critical for preventing catastrophic failure of sensitive power semiconductors such as diodes, thyristors, and IGBT modules. The Type C Flush End configuration features internal metric threads for a high-pressure, low-inductance connection to busbars, minimizing heat generation and energy loss. This model comes integrated with a Type TF mechanical striker, offering clear local indication of fuse operation and the ability to trigger microswitches for remote system diagnostics.

Key Features:

• Ultra-Fast aR Performance: Optimized for the protection of expensive semiconductor junctions against high-energy fault currents.
• High Power Capacity: 1300A rated current, ideal for high-density power electronic applications.
