GVC1-400/630A Vacuum ContactorsPDF

GVC1-400/630A vacuum contactors are mainly used for AC 50-60Hz, the main circuit rated voltage 1140V, the rated current 400A/630A power network systems for remote making and breaking and frequent starting and control of AC motors, transformers and capacitor banks and other occasions.


The vacuum contactor is made of fully enclosed structure, high capacity heat dissipation and high performance component configuration. It has the advantages of stable and reliable mechanical properties, long service life and maintenance. It is especially suitable for locomotive, wind power, variable device used as the main switch side of the switch, cost-effective, is the best alternative to overseas products.


Number of phase: single phase.
Control voltage: AC/DC110V/220V/380V or could be customized.
Product type: the electromagnetic holding type.
Auxiliary circuit contacts: 2NO+1NC.
Auxiliary circuit convention heating current of the auxiliary switch is≤5A.
Control loop mode: the electromagnetic holding type adopts a direct electromagnetic system, the AC control power supply coils work through the rectifier bridge.
