FAQ

Can the AC contactor cut off the short circuit current?
Because the AC contactor is only a switch-type device, no current detection and feedback device, so in practice, often with the appropriate thermal relay or electronic protection device into an electromagnetic starter, in order to protect the circuit may occur overload or phase failure.
A brief introduction to the power contactor
The AC contactor relies on a spring return after power failure. The other half is the activities of the core, the structure and fixed iron core, to drive the main contacts and auxiliary joints of the short
How does the contactor works
The working principle of the DC contactor is somewhat similar to the principle of the temperature switch.
Three-phase AC contactors have several useful clients?
Also note that the voltage applied to the power supply is much (220V or 380V), are generally marked.
What is the difference between a contactor and a circuit breaker?
the main circuit breaker to do protection, its protection is currently more commonly used is the three sections of protection, both overload protection, short circuit short delay, short circuit long delay.
What is the use of AC contactors?
If you want to add self-locking, then you also need to output from the terminal to a terminal connected to the control point above.
What is the difference between a release, a contactor and a circuit breaker?
Detector is a switch circuit breaker or thermal relay inside a body, popular say that some of the monitoring circuit to reach a certain degree of time to trigger the trigger, the purpose is to control the circuit break.
Use Star Triangle to start contactor's order and process method
Press the stop button SB2, the coil KM is out of power, the main contact and the self-locking contact are disconnected, the motor stops.
