Description
Application
ELV_-M series motor protection circuit breakers is mainly used for the overload and short circuit protaction of the motor in AC 50/60Hz, up to 660V, 0.1-80A power circuit, as a full voltage starter and cut off the motor, under the AC3 load or for the overload and short circuit protaction of the circuit and power equipment in the power distribution network.
