Application:

  • DZ518(GV2) Series motor protecting breaker are mainly used fo the overload and shortcircuit protection of the motor in AC 50/60Hz, up to 660V, 0.1-80A power circuit, as a full-voltage starter to start and cut off the motor, under the AC3 load or for the overload and shortcircuit protection of the circuit and power equipment in the power distribution network.
