3P40A general electric contactor 40a dc contactor 36v contactor magnetic

The working principle of contactor is as follows: when the contactor coil is energized, the coil current will generate a magnetic field, which makes the static iron core generate electromagnetic suction to attract the iron core, and drives the AC contactor point action, normally closed contact is disconnected, normally open contact is closed, the two are linked. When the coil is powered off, the electromagnetic attraction disappears, the armature is released under the action of the release spring, so that the contact is restored, normally open contact is disconnected, normally closed contact is closed. Dc contactors work in a similar way to temperature switches.

Application:
* GMC(CJX5) Series AC contactors are latest products in 1990's.
* The series of products for frequency of 50/60Hz, rated insulation voltage up to 690-1000V, rated operational current upto 9A-400A at rated operational voltage up to 380V under AC-3

* GMC Series AC Contactors are mainly used for making breaking electric circuits at a long distance and for frequent

   starting stopping and reversing control of AC motors
* They products comply with IEC947,VDE0660,G814048
