Q:Determine whether the AC contactor can cut off the short circuit current?
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 contactor coil parallel capacitor?
causing the surrounding electronic equipment, especially the PLC's electronic control equipment caused by interference, but also reduce the electrical life of the contacts.
Q:What are the principles of selection of contactors?
When the rated current of the contactor main contact is selected, the rated current of the main contact shall be equal to the rated current of the load
Q:The contactor is mainly composed
20 amperes above the contactor with an arc extinguishing cover, the use of electromagnetic circuit generated when the circuit off, quickly pull off the arc, protect the contacts
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:Three-phase AC contactors have several useful clients?
. And note whether the contact point is normally closed or normally open. If there is self-locking control, according to the principle of the line on it.
Q:What is the use of AC contactors?
The power is applied and the contact point is disconnected after power failure
Q:The main classification of contactors
Permanent magnet AC contactor is a kind of micro-power contactor formed by replacing the traditional electromagnet drive mechanism with permanent magnet drive mechanism
Q:What is the number of AC contactors?
contact system, including three main contacts and one to two groups normally open, normally closed auxiliary
Q:Briefly describe the type of contactor
sub-gate power, commonly known as "electromagnetic action, Magnetic hold, electronic control ". In the process of closing and closing the motion, the electromagnetic attraction
