Mersen PC92UH15C500TF Protistor High-Speed Fuse, 500A 1500VAC, Size 92 aR, Square Body Flush End with Striker (K076163)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 500A 1500VAC

The Mersen PC92UH15C500TF (Reference Number: K076163) is a high-performance ultra-fast-acting fuse from the Protistor® PSC series. It is specifically engineered to provide superior protection for power semiconductor devices, including SCRs, thyristors, and IGBTs. With a current rating of 500A and a high voltage rating of 1500VAC, this fuse is ideal for heavy-duty industrial applications such as high-power rectifiers, traction inverters, and large motor drives.

Built with a high-strength ceramic body and pure silver elements, the PC92UH15C500TF ensures exceptionally low I²t let-through levels, significantly reducing the risk of catastrophic damage to sensitive power electronics during short-circuit events. The flush-end (size 92) square body design allows for easy integration into high-current busbar systems, ensuring a low-inductance connection. This model is equipped with a mechanical striker (Type TF), which provides local trip indication and facilitates the use of external microswitches for remote circuit status monitoring.

Key Features:

• Ultra-Fast Clearance: Optimized aR utilization category for high-speed protection against semiconductor faults.
• High Interrupting Rating: Proven breaking capacity of 200kA at 1500VAC for extreme short-circuit protection.
• Thermal Efficiency: Low power dissipation design helps maintain lower operating temperatures within enclosures.
• Premium Construction: Silver-plated contacts and high-thermal-shock-resistant ceramic housing ensure long-term reliability.
• Integrated Signaling: Includes a built-in striker (TF indicator) for immediate visual confirmation of fuse operation.
