Note: When the contactor is installed in the distribution box, spacers must be assembled on both sides to facilitate heat dissipation.

Working principle.When the coil is electrified, the coil current generates magnetic field, which generates enough electromagnetic suction to overcome the reaction force, and the armature is sucked in to make the contact connected. When the coil voltage disappears or the coil voltage will be low to a certain value, that is, when the so-called release voltage, the magnetic flux generated by the armature end surface decreases, the electromagnetic suction begins to be smaller than the reaction force produced by the reaction spring and the contact spring. The armature of the contactor is released under the action of this reaction force, leaving the yoke, and the contact breaks off immediately.
