CJ19 series contactor is applied to AC 50Hz, rated operating voltage up to 380V power line, and used for low-voltage reactive power compensation equipment or switch off low-voltage parallel capacitors.



They are provided with surge-restrained devices to reduce impulsion of capacitor when switching off surge.

CDC17 series AC contactor is designed for long-distance making and breaking in circuit, and frequently starting and controlling AC motors in power system with frequency 50/60Hz, rated insulation voltage up to 690V and rated operating voltage to 380V in category AC-3. 



It also can be assembled with CDR7 or other thermal relay or electrical protection apparatus, as electron magnetic starter, to protect circuit against overload or phase breaking. It can also be used in the circuit with rated operating voltage of 660V when lowering adequate current.

CJX2 series AC contactor is used for long-distance making and breaking in circuit with frequency 50Hz or 60Hz, rated voltage to 380V and rated current up to 620A"



In combination with thermal relay, it protects circuit against overload as electromagnetic starter. It also functions as delay-type, reversible contactor and star-delta starter when combined with auxiliary contact, air delayer and mechanical interlocking device.
