Mersen PC93UF15C230TF Protistor High-Speed Fuse, 230A 1500VAC, Size 93 aR, Square Body Flush End with Striker (V076355)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 230A 1500VAC

The Mersen PC93UF15C230TF (Reference Number: V076355) is a premium ultra-fast-acting fuse from the Protistor® PSC series, purpose-built for the high-demand protection of power semiconductor devices. This fuse is optimized for 1500VAC applications, providing mission-critical protection for components such as SCRs, thyristors, and IGBTs in high-voltage conversion environments. With a 230A rating and a Size 93 square body, it is a preferred choice for industrial rectifiers, high-power inverters, and UPS systems.

Constructed with a high-grade ceramic body and silver-plated copper contacts, the PC93UF15C230TF ensures high breaking capacity and exceptional thermal management. The "Flush End" design allows for low-inductance busbar mounting, which is essential for minimizing voltage transients during circuit interruption. This model features an integrated mechanical striker (Type TF), facilitating local visual indication and providing the functionality required to drive microswitches for remote system monitoring and automated fault handling.

Key Features:

• Optimal Semiconductor Protection: Utilization category aR provides ultra-fast clearing of short-circuit faults to prevent damage to sensitive electronics.
• High Voltage Rating: Specifically engineered for systems operating at up to 1500VAC, ensuring robust dielectric isolation.
• Compact Square Body Design: Size 93 flush-end configuration allows high current density and space-saving integration into power cabinets.
• Low Energy Let-Through: Minimal I²t values reduce the thermal and mechanical stress on downstream components during a fault.
• Integrated Signaling: Features a reliable TF striker for immediate fault detection and remote signaling via optional microswitches.
