Description:

DC contactor CZ0-400/20TH is mainly used for remote connection and disconnection of DC power lines with rated voltage up to 660V and rated heating current up to 1600A, and are suitable for frequent start, stop, commutation and reverse connection braking of DC motors.
 
The working principle of the DC contactor: When the coil of the contactor is energized, the coil current generates a magnetic field, which makes the static iron core generate electromagnetic attraction to attract the moving iron core, and drives the contact action: the normally closed contact is disconnected, and the normally open contact is closed. is linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contacts: the normally open contact is disconnected, and the normally closed contact is closed.
