What is the energy saving function of traditional contactors?
only the electronic module 0.8mA-1.5mA operating current, which can maximize the savings Electricity, energy-saving rate of up to 99.8% or more
And permanent magnet AC contactor to keep the relays depends on the permanent magnetic force, without the need for electromagnetic current generated by the coil to close the closing
So the closing of the traditional AC contactor must be maintained by the coil to continue to maintain the power, the current from tens to thousands of milliamperes.
once the current becomes smaller so that the resulting electromagnetic force is not enough to overcome the reaction force of the spring, the contactor can not keep the closing state ,
The traditional contactor is held by the closing coil to generate electromagnetic force to overcome the sub-gate spring to achieve
