Mersen PC293UK15C10CTF Protistor High-Speed Fuse, 1000A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker (B076249)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 1000A 1500VAC

The Mersen PC293UK15C10CTF (Reference Number: B076249) is a professional-grade, ultra-fast-acting fuse from the high-capacity Protistor® PSC Square Body series. Engineering specifically for the protection of high-power semiconductor devices, this Size 2x93 dual-body fuse is rated for 1000A at 1500VAC. It serves as a vital safety component for large-scale industrial power electronics, including heavy-duty rectifiers, high-voltage DC drives, massive UPS systems, and traction power converters.

Operating under the "aR" utilization category, this fuse provides specialized partial-range short-circuit protection for sensitive components such as diodes, thyristors, and IGBT modules. It is engineered with extremely low I²t let-through values and fast clearing times to minimize fault energy and prevent terminal damage to semiconductor junctions. The Type C Flush End mounting utilizes internal metric threads for a compact, high-pressure, and low-inductance connection to busbars, ensuring efficient thermal management. This model is equipped with a Type TF mechanical striker, providing reliable local status indication and enabling the integration of microswitches for remote fault signaling and automated system shutdowns.

Key Features:

• Ultra-Fast Acting (aR): Precision-engineered for rapid fault interruption to shield power semiconductors from thermal destruction.
• High Power Capacity: Rated for a continuous current of 1000A, suitable for the most demanding high-current industrial applications.
• 1500VAC High-Voltage Performance: Designed to meet the insulation and interrupting requirements of utility-scale power systems.
• Dual-Body Size 2x93: Robust physical architecture provides balanced current distribution and superior heat dissipation.
• 150kA Breaking Capacity: High interrupt rating ensures the safe isolation of severe short-circuit events at full rated voltage.
• Integrated Monitoring: Features a TF mechanical striker for immediate visual identification of fuse operation and support for remote monitoring.
