Q: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

Q:The main structure of the contactor

20A above the contactor with an arc extinguishing cover, the use of the circuit when the electromagnetic force generated by breaking, quickly pull off the arc, the protection of contacts

Q:What is the use of AC contactors?

Second: First, we should know the principle of AC contactor. He is using external power to the coil, resulting in electromagnetic fields.

Q:Judge the contactor is good or bad

the amount of power to control the end of the line to remove the control, with a multimeter to beat the amount of foot, press the test end of the three main contacts and another group of normally open contacts, should be conductive

Q:What is the contactor's formula?

The rated current and rated voltage of the low voltage circuit breaker shall not be less than the normal operating voltage of the line and the calculated load current (the total current at all load operation, multiplied by the actual situation)

Q:What does the contactor NC ON mean?

the arc extinguishing device, the general capacity of the larger AC contactor are equipped with arc extinguishing device, in order to quickly cut off the arc, from burning the main contact

Q:What is the effect of the open contact of the AC contactor and the pushbutton switch?

When the start button is pressed, the contactor coil is energized. When released, the contactor coil is de-energized and disconnected

Q:What is the difference between the contactor and the relay?

Electromagnetic relays and contactors, their working principle should be said to be the same

Q:What causes the AC contactor to be damaged

Operation circuit power supply capacity is insufficient or disconnected, wiring error and control contact bad contact 3. The coil technical parameters are not in accordance with the conditions of use

Q:What is the effect of the contactor coil parallel capacitor?

Capacitors at both ends of the voltage can not be special changes, and the capacitor can delay and reduce the coil's reverse electromotive force, Reduce interference, extend the life of contacts.
