Mersen PC91UF15C160TF Protistor High-Speed Fuse, 160A 1500VAC, size 91 aR, Square Body Flush End with Striker (Y076151)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 160A 1500VAC

The Mersen PC91UF15C160TF (Part Number: Y076151) is a high-performance Protistor® square body fuse-link designed specifically for the protection of power semiconductor devices. Engineered for 1500VAC applications, this Size 91 fuse provides superior flexibility and ultimate protection for modern power conversion equipment, including SCRs, diodes, thyristors, GTOs, and IGBT devices.

Constructed with pure silver die-cut elements embedded in solidified sand, the fuse ensures precision control over arcing characteristics, resulting in low I²t values and exceptionally high breaking capacity. The silver-plated brass contact surfaces and non-magnetic hardware ensure reliable electrical conductivity and minimize thermal losses.

Key Features:

• High Breaking Capacity: Rated up to 200kA to handle high-fault current conditions.
• Advanced Indication: Features an integrated low-voltage trip-indicator (Striker) for visual status or integration with a field-mountable microswitch.
• Precision Engineering: aR characteristic specifically optimized for high-speed semiconductor circuit protection.
• Durable Construction: Ceramic body insulating material provides high thermal and mechanical stability.
• Flush End Mounting: Metric thread flush-end terminals for secure, low-resistance bolted connections.
