Mersen PC93UK15C500TF Protistor High-Speed Fuse, 500A 1500VAC, Size 93 gK, Square Body Flush End with Striker (E076364)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 500A 1500VAC

The Mersen PC93UK15C500TF (Reference Number: E076364) is a specialized ultra-fast-acting fuse from the Protistor® PSC series, engineered for the comprehensive protection of power semiconductor devices. Rated at 500A and 1500VAC, this Size 93 square-body fuse is a critical component for high-power industrial applications, including large-capacity rectifiers, railway traction systems, and high-voltage motor drives.

As a "gK" utilization category fuse, it provides full-range protection, capable of safely clearing both low-level overloads and high-magnitude short-circuit currents. Its Flush End (threaded) contact design ensures a secure, low-resistance interface for busbar mounting, optimizing thermal dissipation and electrical conductivity. This model features an integrated mechanical Type TF striker, which functions as a visible trip indicator and can be utilized with microswitches for remote status monitoring.

Key Features:

• Full-Range gK Protection: Designed to protect semiconductor circuits across the entire overcurrent spectrum, minimizing downtime and component damage.
• Exceptional Breaking Capacity: Certified to interrupt fault currents up to 150kA at 1500VAC, providing robust safety in high-energy environments.
• Low I²t Let-Through: Advanced internal silver-element geometry limits thermal energy during faults, safeguarding sensitive electronics from excessive stress.
• Industrial Durability: Constructed with premium ceramic bodies and silver-plated copper contacts to withstand demanding thermal cycles and harsh environments.
• Remote Signaling Capability: Includes a built-in TF striker for immediate visual indication and integration with automated system controls.
