Mersen PC93UF15C350TF Protistor High-Speed Fuse, 350A 1500VAC, Size 93 aR, Square Body Flush End with Striker (A076360)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 350A 1500VAC

The Mersen PC93UF15C350TF (Reference Number: A076360) is an ultra-fast acting fuse engineered for the high-performance protection of power semiconductor devices. Part of the Protistor® PSC series, it is specifically designed to safeguard sensitive components such as thyristors, SCRs, and IGBTs from the destructive effects of overcurrent and short-circuit faults. Rated for 1500VAC, this Size 93 square-body fuse is ideal for high-power industrial systems, including large-scale rectifiers, motor drives, and advanced traction power supplies.

This fuse features a Flush End contact design, facilitating low-inductance mounting directly to busbars, which is critical for suppressing transient voltage surges during fault clearing. Constructed with premium ceramic materials and silver-plated copper terminals, it ensures excellent heat dissipation and mechanical durability in harsh electrical environments. The integrated Type TF striker provides a reliable visual indicator of fuse operation and is compatible with remote signaling microswitches, ensuring minimal downtime and rapid system diagnostics.

Key Features:

• Ultra-Fast Fast-Acting Protection: Utilization category aR provides the necessary rapid response to protect power semiconductors from high-intensity faults.
• High Voltage Capacity: Engineered for 1500VAC applications, meeting the requirements of high-density industrial power conversion.
