Fusesaver, the world’s fastest MV outdoor vacuum circuit breaker, is the most cost effective solution for optimizing reliability while minimizing operating costs of rural overhead MV networks.

Fusesaver is a new class of intelligent, compact and low cost single phase circuit breaker that minimizes lost customer minutes by protecting lateral line* fuses from blowing on transient faults. With on-board micro-processor control and wireless connectivity, Fusesaver has configurable protection, multi-phase operation functions, on-board event history and can be integrated into a SCADA system for remote control.
