Capacitor switching switch

CJX2 AC contactor

The AC contactor has the advantages of small size, light weight, long life, low power consumption, and can be combined and derived as required. It can be equipped with building block auxiliary contact groups, air delay heads, mechanical interlocking mechanisms and other accessories to form a delay contactor, Star-delta starter, and can be directly plugged into and installed with thermal overload relay to form an electromagnetic starter. The product can be installed with screws, and can also be installed with 35mm (75mm) standard rails.

Detailed introduction

CJX2 AC contactor

Main purposes and scope of application
CJX2 series AC contactors are mainly used for AC 50Hz or 60Hz, rated insulation voltage 690V, in the AC-3 use category, rated working voltage 380V rated working current to 95A power system, for remote connection And break the circuit and frequently start and control the AC motor. It can be combined with an appropriate thermal overload relay or electronic protection device to form an electromagnetic starter to protect the circuit that may be overloaded.
This product complies with: national standards GB/T14048.1, GB14048.4, GB 14048.5.
