AC vacuum contactor outline and installation dimension (Unit: mm)

Tips: Structural characteristics of ac vacuum contactor

The ac vacuum contactor is composed of a magnetic system, a contact system, and an auxiliary contact.
The ac vacuum contactor is a three-dimensional structure, the upper part is the contact system, and the lower part is the electromagnetic system.
The magnetic system of the ac vacuum contactor is composed of a coil, an iron core and a rectifier, and is installed in a base made of cast aluminum alloy or DMC.
The ac vacuum contactor is a plane structure, the left part is the contact system, and the right part is the electromagnetic system.
The contact system of the ac vacuum contactor is composed of moving and static contacts and a vacuum interrupter, which is installed in a base made of insulating materials.
The vacuum interrupter adopts new contact materials for one-time sealing and discharge, and the electromagnetic system adopts DC double coils.
