Working principle

The working principle of the contactor: Upon energization, the circuit with current will create a magnetic field and generate sufficient magnetic adhesion to overcome counterforce, close armature and connect the contacts. When the coil voltage dies out or reduces to a certain value(i.e. at the state of voltage release), for the flux generated at the end face of the armature decreases, the magnetic adhesion becomes weaker than the counterforce generated by the reaction spring, contact spring, etc. Under the counterforce, the armature will be released and free from th efield yoke, and then the contacts will be disconnected.
