VM1 – Vacuum circuit-breaker with magnetic actuator, low/mid duty

Vacuum circuit-breakers of type VM1 find universal applications in medium voltage range. Their innovative permanent magnetic actuator facilitates a drastic reduction in the number of parts, thus high reliability and sturdiness. An electronic controller with sensors monitors all the functions of the circuit-breaker and its own functional reliability. VM1 technology provides the optimum solution for extremely high number of switching operations including freedom from maintenance as a standard feature.
