CKG3-12 Vacuum Contactor 3p

CKG3-12 Vacuum Contactor 3 polesis suitable for an AC 50-60 Hz electric power system, with highest operating voltage of 12 kV, for direct or remote on-off control of the main circuit.

Especially suitable for controlling of frequently operated of the motor, or other loads. It features of reliability, long lifetime, less maintenance, and safety. It has proven the very obvious economic benefit with this kind of product to replace the conventional products.

This series of vacuum contactors main used below the rated current from 160A-1600A power network systems for remote making and breaking and frequent starting and control of AC motors, transformers and capacitor banks and other occasions.
