Q:What is the formulation of the contactor?

When controlling the motor, the rated current of the main contact should be greater or slightly larger than the rated current of the motor

Q:With long life, long reliability is the advantages of traditional communication contactor

but also has the role of magnetic repulsion, these two functions so that the opening speed is much faster than the traditional contactor

Q:What is the difference between the auxiliary system 01 and 10 of the AC contactor?

The so-called normally open contact is the contactor coil without electricity in the case of moving, static contact is separate, non-conductive, generally used NO said, normal open

Q:he three-phase AC contactor has several wiring ports

Usually three-phase AC contactor upper and lower ends have three main lines, two sets of auxiliary contact terminals and a set of control coil side,

Q:How to connect the DC contactor to the circuit?

Have you seen the satellite days someone to close the knife? Dangerous high-current gate knife when the arc is wounding

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

Long connection, that is, on the basis of the jog, stop the button on the back and then connect a line to the contactor normally open the end of the auxiliary contact, the other end of the auxiliary contact connected to the coil contacts, This contact is connected to the start button

Q:Get the method of the relay time parameter

This method can detect the time parameters such as relay action time, action hopping time, release time, release back time

Q:How do I distinguish between contactors and circuit breakers?

of course, there will be some heaters, dual power supply switching and other occasions to use. The continuity of the contactor is achieved by controlling the coil voltage

Q:By the drive system, contact systems, arc and other components of the connector.

arc extinguishing system: arc extinguishing device used to ensure that the contact disconnect the circuit

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.
