Mersen PC292UK15C700TF Protistor High-Speed Fuse, 700A 1500VAC, Size 2x92 aR, Square Body Flush End with Striker (T076242)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 700A 1500VAC

The Mersen PC292UK15C700TF (Reference Number: T076242) is a high-performance, ultra-fast-acting semiconductor protection fuse within the world-renowned Protistor® PSC Square Body series. This Size 2x92 dual-body fuse is specifically engineered to handle a rated current of 700A and a high voltage of 1500VAC. It is designed for the rigorous protection requirements of large-scale power conversion equipment, including industrial rectifiers, high-power converters, and railway traction systems.

Classified under the "aR" utilization category, this fuse provides targeted short-circuit protection for power semiconductors such as diodes, thyristors, and IGBT modules. It features extremely low I²t let-through values, ensuring that peak fault energy is cleared rapidly to prevent downstream component destruction. The Square Body Flush End (Type C) configuration utilizes internal metric threads for low-inductance mounting, offering superior electrical and thermal contact. This model is equipped with a mechanical Type TF striker, facilitating both local visual indication and remote fault signaling via auxiliary microswitches.

Key Features:

• High-Speed Protection: Advanced aR utilization category optimized for the protection of sensitive power electronics.
• High Voltage Capacity: Rated for 1500VAC, making it suitable for high-voltage industrial and energy infrastructure.
• Dual Body Construction: The Size 2x92 geometry offers a robust power-to-size ratio with excellent heat dissipation.
• Superior Interruption Rating: Certified breaking capacity of 150kA at 1500VAC safely manages severe short-circuit events.
• Minimal Energy Loss: Engineered with high-grade silver-plated copper contacts to ensure low power dissipation during continuous operation.
• Remote Signaling Capability: Built-in TF striker allows for immediate fault indication and integration into automated monitoring systems.
