Q:On the difference between the contactor and the relay
The relay will be used as a contactor, but if a main circuit current is very large, so that The use of on-off main circuit contactor capacity is very large
Q:What is the power contactor
AC contactor using the main contact to open and close the circuit, with auxiliary contacts to control the implementation of instructions.
Q:What is the traditional AC contactor contact that does not vibrate?
When the voltage fluctuates in the critical state of closing and opening, the contactor is in the same way, Vibration, resulting in contact welding or burned, leaving the motor burned.
Q:How does the contactor works
The working principle of the contactor is that when the contactor coil is energized, the coil current generates a magnetic field
Q:What types of contactors can be divided into?
magnet combined with the combination of operating mechanism, not just the use of the original electromagnetic Suction and spring reaction as the core of the pull and separation of powe
Q:What parts of the contactor
AC contactor is made as a whole, shape and performance are constantly improving, but the function is always the same.
Q:Similar terms for contactors and relays
Therefore, as the first floor of a friend said, large capacity of the contactor are generally equipped with an arc cover (because the high current disconnect will produce arc, do not use arc extinguishing, head).
Q:What causes the AC contactor to be damaged
Damage to the product itself (such as the coil broken or burned, the mechanical moving part was stuck, the shaft rust or skew, etc.) 5. Contact spring pressure and overtravel. Increase the supply voltage
Q:The key structure of the contactor
Semiconductor contactor: The semiconductor contactor is a contactor that performs current operation by changing the conduction state and the open state of the circuit 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.
