LC1-F 400A Ac contactor for power distribution box 
contactor worked principle : when the contactor coil is energized, the coil current will generate a magnetic field,
The generated magnetic field makes the static iron core generate electromagnetic attraction to attract the moving iron core, and drives the AC contactor point to act. The normally closed contact is open, and the normally open contact is closed. The two are linked. When the coil is de energized, the electromagnetic attraction disappears, and the armature is released under the action of the release spring, so that the contact is restored, the normally open contact is opened, and the normally closed contact is closed. The working principle of DC contactor is similar to that of temperature switch
The series JKC1 AC contactor is applicable at the line of AC 50/60 Hz, rated voltage up to 660V and rated current up to 95A for remote switch, breaking and frequent starting, controlling the AC motor. Moreover, the contactor can act as the time-delay contactor, reve-rsible contactor, star-delta starter by the accessories addition such as addition of modular auxiliary contact set. Air timedelay head, mechanical interlock mechanism, etc. Moreover, it could act as the electromagnetic starter by the direct plug of the thermal relay
