Mersen PC293UB15C15CTF Protistor High-Speed Fuse, 1500A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker

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

The Mersen PC293UB15C15CTF is a premium ultra-fast acting fuse belonging to the Protistor® PSC Square Body series. Engineering specifically for the state-of-the-art protection of high-power semiconductor devices, this Size 2x93 dual-body fuse is rated for a continuous current of 1500A at 1500VAC. It is an indispensable safety component for high-capacity industrial power electronics, including large-scale rectifiers, railway traction converters, high-voltage DC motor drives, and utility-grade uninterruptible power supplies (UPS).

Designed under the "aR" utilization category, this fuse provides specialized partial-range short-circuit protection for sensitive semiconductors like diodes, thyristors, and IGBTs. It is defined by its exceptionally low I²t let-through values and peak let-through current, ensuring minimal energy release during a fault to prevent catastrophic component failure. The Type C Flush End mounting utilizes internal metric threads to provide a robust, low-impedance connection directly to busbars, facilitating superior heat dissipation. This model includes an integrated Type TF mechanical striker, which provides both a local visual indication of a blown fuse and the ability to operate an optional microswitch for remote fault monitoring and system protection logic.

Key Features:

• Ultra-Fast acting (aR): Precision-designed to interrupt fault currents with extreme speed, protecting delicate semiconductor junctions.
• Maximum Current Density: 1500A rated current for heavy-duty, high-performance power distribution systems.
• 1500VAC Rated voltage: Built to handle the insulation and quenching requirements of high-voltage industrial circuits.
• Dual-Body Size 2x93: Enhanced physical structure provides optimized cooling and current sharing across the internal elements.
• Superior Breaking Capacity: 150kA interrupt rating ensures reliable clearing of even the most severe short-circuit faults.
• System Integration: Features a TF striker for rapid troubleshooting and seamless integration with remote signaling systems.
