AC contactor AC contactor is widely used in low voltage circuits, is a safe, easy to control, CNC Electric volume and a wide range of industrial necessities. Now commonly used in the rated current 63A and above large, medium-capacity AC contactor should more than million Taiwan dollars electric energy meter, its operating system at the time of retention of electromagnetic active power consumed between 10W ~ 100W; reactive power consumed in the Dole circuit breakers spent tens to hundreds of spent between Seoul. The active power consumption distribution is roughly: 65% to 75% of the core, the short-circuit ring 25% to 30%, the coil 3% to 5%. For such a being in the industrialization and urbanization of exchanges and contacts with large country, and the energy needs of the growing tension, saving power resources has become imperative.
Such as the AC contactor solenoid operating system with an appropriate energy-saving technology to its operating system, the original design of electromagnetic ac to dc retention retention, core and short ring can save most of the loss in power, to obtain a high energy-saving efficiency (typically active saving rate> 90%). Moreover, through the Switchgear & Substation transformation can reduce or eliminate noise, reduce the temperature rise of the coil and extend the service life of the contactor.
