Mersen PC92UK15C315TF Protistor High-Speed Fuse, 315A 1500VAC, Size 92 aR, Square Body Flush End with Striker (H076160)

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

The Mersen PC92UK15C315TF (Part Number: H076160) is a premium ultra-fast square body fuse-link from the Protistor® PSC series. This Size 92 component is engineered for the high-capacity protection of power conversion semiconductors, including SCRs, diodes, thyristors, GTOs, and IGBT devices. It is optimized for 1500VAC industrial systems requiring a 315A current rating.

This fuse-link utilizes the UK type design, featuring pure silver die-cut elements embedded in solidified sand. This construction ensures precise arcing control, providing very low I²t levels and a high breaking capacity of 200kA. The high-strength ceramic body and silver-plated contact surfaces offer chemical and thermal stability in demanding environments. Each unit comes equipped with a low-voltage trip-indicator (striker) for immediate visual identification of fuse operation, which can also activate an optional field-mountable microswitch for remote fault signaling.

Key Features:

• Extremely Fast-Acting: aR utilization category designed specifically for ultra-high-speed semiconductor short-circuit protection.
• High Interrupting Rating: Capable of safely breaking currents up to 200kA at 1500VAC.
• Low Energy Let-Through: Minimizes I²t to protect sensitive downstream electronic components from thermal damage.
• Flush-End Mounting: Square body design with metric threaded flush terminals for high-torque, reliable electrical connections.
• Integrated Status Indication: Mechanical striker system supports both local visual confirmation and remote electronic monitoring via microswitch.
