Mersen PC93UF15C315TF Protistor High-Speed Fuse, 315A 1500VAC, Size 93 aR, Square Body Flush End with Striker (Z076359)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 315A 1500VAC

The Mersen PC93UF15C315TF (Reference Number: Z076359) 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 IGBT modules. This fuse is optimized for high-voltage industrial applications up to 1500VAC, where rapid fault clearing and high breaking capacity are essential to prevent catastrophic equipment failure and minimize downtime.

Designed with a Size 93 square body and flush-end bolted contacts, the PC93UF15C315TF ensures a high-integrity, low-resistance electrical connection suitable for heavy-duty busbar mounting. The internal architecture utilizes silver fuse elements and advanced arc-quenching materials to provide extremely low I²t let-through values. It features an integrated mechanical striker (Type TF), which serves as a visual trip indicator and can be utilized to trigger a microswitch for remote fault detection and system isolation.

Key Features:

• Ultra-Fast Acting Protection: Classified under utilization category aR, tailored for the high-speed requirements of semiconductor circuitry.
• High Interrupting Rating: Features a massive breaking capacity of 150kA, ensuring safe circuit interruption even under severe short-circuit conditions.
• Superior Thermal Performance: Designed with high-quality ceramic and silver-plated copper for optimal heat dissipation and long-term reliability.
• Low Energy Let-Through: Specifically calibrated to limit thermal and electromagnetic stress on downstream power electronics.
• Integrated Monitoring Capability: Equipped with a built-in TF striker for immediate local status indication and compatibility with auxiliary signaling switches.
