Mersen PC93UK15C400TF Protistor High-Speed Fuse, 400A 1500VAC, Size 93 gK, Square Body Flush End with Striker (C076362)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 400A 1500VAC

The Mersen PC93UK15C400TF (Reference Number: C076362) is a high-capacity, ultra-fast-acting fuse from the Protistor® PSC series, designed for the advanced protection of power semiconductor devices. With a 400A rating and 1500VAC voltage capacity, this Size 93 square-body fuse is engineered for heavy-duty industrial environments, including power converters, railway traction systems, and high-voltage motor drives.

As a "gK" utilization category fuse, it provides specialized full-range protection, effectively managing both low-level overloads and high-level short-circuit currents. The Flush End (threaded) contact design ensures a stable, low-resistance electrical interface, minimizing power loss and heat generation at the connection points. This model is equipped with a mechanical Type TF striker, serving as both a visual status indicator and a trigger for microswitches to enable remote system monitoring and automatic circuit isolation.

Key Features:

• Full-Range gK Protection: Expertly calibrated to protect high-voltage semiconductor circuits against the entire spectrum of overcurrent conditions.
• High Interrupting Capacity: Rated to safely quench fault currents up to 150kA at 1500VAC, ensuring maximum safety for high-power installations.
• Premium Construction: Utilizing high-grade ceramic and silver-plated copper components for enhanced durability and superior thermal management.
• Minimal I²t Let-Through: Advanced internal silver element geometry limits energy throughput during faults, protecting sensitive power electronics from thermal shock.
• Integrated Fault Signaling: Includes a built-in TF striker for immediate local indication and seamless integration with industrial monitoring systems.
