Pictures for Elevator Spare Parts neider Contactor LC1D50AFD TesSys DC110V Contactor 3P 50A
The vacuum contactor uses vacuum as the arc extinguishing medium, and its main contacts are sealed in a special vacuum interrupter. When the operating coil is energized, the armature pulls in, and the contact is closed under the action of the contact spring and the self-closing force of the vacuum tube; when the operating coil is powered off, the counter force spring overcomes the self-closing force of the vacuum tube to release the armature, and the contact is disconnected. When the contactor breaks the current, platinum scale formed by metal vapor will be formed in the contact gap, which will affect the service life of the contactor.
