Circuits Diagram

Tips: Working principle of DC contactor
When the DC contactor coil is energized, the coil current generates a magnetic field, which causes the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the contact action: the normally closed contact is disconnected, and the normally open contact is closed. The two are linked. When the coil is de-energized, the electromagnetic attraction force 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.
12V 24V 48V 220V DC contactor works to connect and break of the circuit load, which can fully meet the special demand of electric locomotive, diesel locomotive and electric motor car group. 3 pole (3NO) or 4 pole (2NO+2NC) contact form, 32 amp, high performance and low price.
