Basic Info

Model No.:  CKG

Product Description

Model NO.: CKG Number of Pole: 3 Main Circuit Rating Voltage: High Voltage Type: Ac Contactors Features: Small Size, Light Weight,Ect Specification: small Electricity Type: Vacuum Phase: 3 Main Circuit Rating Current: 630A Applied: Control Motor, Transformer Ect Trademark: YF Origin: Jiangyin Yunfeng, China Product Overview
CKG series high voltage vacuum contactor is suitable for electrical system with AC 50~60Hz, rated voltage 7.2~12kV, rated current 630A. It has the function of making and breaking circuit in direct or remote controlling way.
Single pole contactor can play the role of protection when it making circuit to earth. This kind of contactor is particularly applied to load of electrical control occasion like control motor, transformer and ect. It has advantage of strong ability of arc extinguishing,  good pressure performance, high-frequency operation, small size and light weight, long service life and ect.
