Mersen PC93UJ15C700TF Protistor High-Speed Fuse, 700A 1500VAC, Size 93 aR, Square Body Flush End with Striker (B076131)

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

The Mersen PC93UJ15C700TF (Reference Number: B076131) is a high-performance ultra-fast-acting fuse from the Protistor® PSC series, specifically engineered for the protection of large-scale power semiconductor devices. With a robust current rating of 700A and a high-voltage capacity of 1500VAC, this Size 93 square-body fuse is a critical safety component for demanding industrial power electronics, including high-power rectifiers, heavy-duty motor drives, and renewable energy inverters.

Adhering to the "aR" utilization category, this fuse provides exceptional short-circuit protection with extremely rapid response times. Its Square Body Flush End design facilitates a high-pressure contact interface via metric internal threads, ensuring superior electrical conductivity and low power loss during continuous operation. This model is equipped with an integrated mechanical Type TF striker, which serves as a reliable trip indicator and can be used to actuate auxiliary microswitches for remote system diagnostics and fault reporting.

Key Features:

• Ultra-Fast aR Protection: High-speed interruption profile specifically tuned to protect sensitive power semiconductors like diodes, thyristors, and IGBTs.
• High Interrupting Rating: Certified breaking capacity of 150kA at 1500VAC, providing maximum safety in high-energy fault conditions.
• Thermal Efficiency: Engineered for low power dissipation and minimal I²t let-through, protecting downstream components from excessive thermal and mechanical stress.
• Robust Industrial Build: Constructed with a high-strength ceramic body and silver-plated copper contact surfaces for maximum durability and corrosion resistance.
• Integrated Monitoring: Features a built-in TF striker for immediate local status indication and seamless integration with industrial monitoring systems.
