AC AND DC CONTACTOR WITH DEAD CURRENT DURING RUNING

The utility model relates to an AC and DC contactor without voltage or current during running which is the improvement for an original contactor. A lock system is composed of a U-shaped turning plate, a reset electrical magnet and a closing spring. A traction system is composed of a miniature cylindrical iron core and a coil. Therefore, when the AC and DC contactor runs, no voltage or current passes through the coil, no power is consumed, and electricity is saved. The traction system uses the miniature cylindrical iron core and the coil to replace a silicon steel sheet which is in a shape like the Chinese character 'shan' and a big coil which have high price. The utility model has the advantages of simple production process, low cost, etc. The AC and DC contactor of the utility model can be easily reconstructed on the basis of an original contactor and can be matched with various leakage protectors.
