Mersen PC93UK15C450TF Protistor High-Speed Fuse, 450A 1500VAC, Size 93 gK, Square Body Flush End with Striker (D076363)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 450A 1500VAC

The Mersen PC93UK15C450TF (Reference Number: D076363) is a high-performance ultra-fast-acting fuse from the Protistor® PSC series, engineered for the comprehensive protection of power semiconductor devices. With a high current rating of 450A and a voltage capacity of 1500VAC, this Size 93 square-body fuse is designed to meet the rigorous demands of industrial power electronics, including large-scale rectifiers, high-voltage inverters, and heavy-duty traction power supplies.

Classified under the "gK" utilization category, this fuse provides specialized full-range protection, effectively intercepting both low-level overloads and high-magnitude short-circuit faults. The Flush End (threaded) contact design allows for direct, low-inductance mounting to busbars, which is essential for minimizing voltage spikes and maximizing electrical efficiency. It features an integrated mechanical Type TF striker, which enables clear local status indication and is fully compatible with microswitches for remote fault signaling and system automation.

Key Features:

• Full-Range gK Protection: Optimized to safeguard high-power semiconductor circuits against the entire overcurrent spectrum, from minor overloads to catastrophic short circuits.
• High Interrupting Rating: Validated for a breaking capacity of up to 150kA at 1500VAC, providing elite-level safety for high-energy industrial installations.
• Superior Thermal Performance: Constructed with high-purity ceramic materials and silver-plated copper terminals to ensure stable operation and longevity in high-heat environments.
• Low I²t Let-Through: Precision-engineered internal silver elements limit thermal energy transfer during a fault, protecting sensitive components like IGBTs and Thyristors.
• System Integration Ready: Includes a built-in TF striker for visual fault confirmation and seamless integration into remote monitoring circuits.
