Mersen PC73UD13C700TF / R300510 Protistor Size 73 aR High-Speed Fuse, 700A, 1250VAC

The Mersen PC73UD13C700TF (Reference Number: R300510) is a high-performance Protistor® square body fuse-link, specifically engineered for the ultra-fast-acting protection of power semiconductor devices. This Size 73 fuse is optimized for high-power rectification, static converters, and DC-coupled energy systems where sensitive components like thyristors and IGBTs require immediate isolation during fault conditions. Rated for 1250VAC and boasting a high breaking capacity of 126kA, it minimizes energy let-through to ensure maximum safety for semiconductor stacks. The TTF (Tapped Terminal Face) design features M12 threaded holes for space-saving, low-resistance connections in compact industrial architectures.
