- Briefly describe the type of contactor
- One, permanent magnet actuator to save a lot of energy to maintain the coil power consumption, environmental protection and energy conservation.
- Contactor mainly by the drive system, contact system, arc and other components.
- and auxiliary contact is in the control loop to meet the requirements of various control methods
- Various types of contactors are classified
- DC contactor as a widely used one of the electrical switch, the production and the demand for a huge number, in the normal use of the process
- What types of contactors can be divided into?

- How to measure the contactor is good or bad
- Look: A, see if it works. B, boot, such as contactor pull, then the fan work, press does not work (set the capacitor is good), can initially determine the contactor bad
- How does the contactor interlock?
- if the two contactor at the same time pull, will occur between the power phase and phase short circuit.
- Three-phase AC contactor has several terminals that have a role
- The power is applied and the contact point is disconnected after power failure
