Overview

The Mersen S076307 Protistor® is a high-speed cylindrical fuse-link engineered for semiconductor protection in DC applications. This 27x60mm gR (gRB) fuse is rated for 660VDC and 110A, featuring a striker mechanism for immediate visual indication of fuse operation. Designed for modern DC equipment, it delivers robust protection against overcurrents and short circuits with a rated breaking capacity of 90 kA. The fuse minimizes damage during faults with lower I²t values (27,000 A²s pre-arcing, 90,000 A²s clearing) and reduces power dissipation to 14W at rated current for extended operational life. Its compact 27x60mm size and 660VDC rating make it ideal for railway power and auxiliary circuits, where reliability and quick maintenance diagnostics are critical. The striker ensures fast fault identification, while the high breaking capacity provides dependable protection in demanding environments.
