High performance mechanical interlocking contactor is an electrically controlled switch constructed with a mechanical interlock and two revering contactor, which is used for long distance breaking circuit and frequently starting or control the motor.

Specification

Tips:

AC contactors are widely used as power switching and control circuits. The main contacts are used to open and close the circuits, and the auxiliary contacts are used to execute control commands. The main contact generally has only a normally open contact, and the auxiliary contact often has two pairs of contacts with normally open and normally closed functions. Small contactors are often used as intermediate relays to cooperate with the main circuit. The contacts of the AC contactor are made of silver-tungsten alloy, which has good electrical conductivity and high temperature ablation resistance. The working principle of the AC contactor is to use the electromagnetic force and the spring force to cooperate to realize the connection and disconnection of the contacts. The AC contactor has two working states: power-off state (release state) and energized state (action state). When the attraction coil is energized, the static iron core generates electromagnetic attraction, the armature is attracted, and the connecting rod connected to the armature drives the contact action, so that the normally closed contact break contactor is in the energized state; when the attraction coil is de-energized, The electromagnetic attraction disappears, the armature is reopening, so that the normally open contact is closed, and released under the action of the position spring, all the contacts are reset accordingly, and the contactor is in a power-off state.
