Mersen PC293UJ15C14CTF Protistor High-Speed Fuse, 1400A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 1400A 1500VAC

The Mersen PC293UJ15C14CTF is an ultra-fast acting high-power fuse designed as part of the specialized Protistor® PSC Square Body series. Engineering specifically for the rigorous protection requirements of power semiconductor devices, this Size 2x93 dual-body fuse is rated for a continuous current of 1400A at 1500VAC. It is a critical component for high-voltage industrial systems, including massive power converters, traction substations, heavy-duty rectifiers, and renewable energy grid inverters.

Adhering to the "aR" utilization category, this fuse provides precise partial-range short-circuit protection for sensitive electronic components such as diodes, thyristors, and IGBT modules. It features extremely low I²t and peak let-through current values, minimizing the thermal and mechanical stress on downstream equipment during a fault. The Type C Flush End design provides internal metric threads for a secure, low-resistance mechanical interface with busbars, optimizing electrical conductivity and reliability. This model is equipped with a Type TF mechanical striker, enabling integrated local visual status and providing a platform for microswitch mounting for remote fault notification and automated system control.

Key Features:

• Ultra-Fast acting (aR): Specifically engineered to interrupt fault currents rapidly, shielding expensive semiconductor junctions from damage.
• High Current Capacity: 1400A rating provides robust performance for heavy industrial and utility-scale power applications.
• 1500VAC High-Voltage Rating: Optimized for safe operation in advanced high-voltage energy storage and distribution networks.
