Q:What does the contactor lock mean?

t is through the start button (jog) after the start of the contactor coil to continue to have electricity, resulting in maintaining the contact path state

Q:What about the number of AC contactors?

When the coil is powered off, the suction disappears, and the moving core interlocking part is separated by the reaction force of the spring

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:What are the principles of selection of contactors?

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:What is the number of AC contactors?

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:Contactor accessories have what roles?

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 difference between the contactor and the relay?

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

Q:How to measure the contactor is good or bad

Such as one of the work, the other does not work can be roughly determined to contact bad.

Q:How does the contactor interlock?

Interlocking is the two contactors can not be connected at the same time, generally used in the motor reversing circuit

Q:Three-phase AC contactor has several terminals that have a role

Output and input are corresponding, it is easy to see. 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
