Mersen PC293UK15C800TF Protistor High-Speed Fuse, 800A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker (Z076247)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 800A 1500VAC

The Mersen PC293UK15C800TF (Reference Number: Z076247) is a premium ultra-fast-acting industrial fuse part of the Protistor® PSC Square Body product line. Specifically engineered for the protection of high-power semiconductor devices, this Size 2x93 dual-body fuse is rated for 800A at 1500VAC. It is a critical safety component for high-performance power electronics, including large-scale AC/DC drives, industrial rectifiers, UPS systems, and traction power substations.

Classified as an "aR" utilization category fuse, this unit provides specialized partial-range short-circuit protection. It is designed with extremely low I²t (thermal energy let-through) and peak let-through current characteristics, ensuring that sensitive power semiconductors like thyristors, diodes, and IGBTs are shielded from the destructive effects of high-energy electrical faults. The Type C Flush End design provides internal metric threads for robust, low-inductance busbar mounting, optimizing thermal and electrical conductivity. This model features an integrated Type TF mechanical striker, providing both local visual indication and the capability to trigger remote microswitches for real-time status monitoring.

Key Features:

• Ultra-Fast Response: Specifically tuned aR characteristic for exceptional speed in fault clearing and semiconductor protection.
• High Power Capacity: Supports continuous current of 800A, designed for heavy-duty industrial energy conversion.
• 1500VAC Optimization: Engineered for high-voltage isolation and safety in utility-grade power applications.
• Dual Body Size 2x93: Robust physical architecture ensures efficient cooling and long-term stability under high thermal loads.
• Superior Interruption Capability: High breaking capacity of 150kA ensures safe shutdown during severe short-circuit events.
• Integrated Fault Signaling: Includes a TF mechanical striker for immediate identification of fuse operation.
