CJ12 AC Contactor

CJ12 AC Contactor is mainly used for electric equipment of metallurgy, electric power and hoister. It is suitable for the circuit of AC 50/60Hz, the voltage up to 380V, current up to 600A for remove making and breaking circuit, and frequency starting, stopping and inverse AC motor. The products comply with IEC60947-4.

Product Overview

CJ12 AC contactor is used for the circuit of AC 50 Hz, rated voltage to 380V, current up to 600A of power systems, for remove making and breaking circuit, and frequency starting, stopping and inverse AC motor. Mainly used for electrical control circuits of metallurgy, rolling steel, cranes and other electrical equipment.

Din Rail Mounted Contactor meets the standards of GB14048.4 and IEC60947-4-1.


Model Description


Normal Operating Conditions

1. Ambient temperature: Ambient temperature is not higher than +40°C and not lower than -25°C (can be used at +60°C, but the rated current of contact should be reduced).

2. Altitude: no more than 2000m.

3. Relative humidity is not more than 90% (Monthly average minimum temperature does not exceed +25°C).

4. Amplitude is less than 6mm, vibration frequency is not greater than 3Hz occasions.

5. The inclination of the mounting surface to the vertical or forward or backward shall not exceed 5°.

6. Pollution degree: 3.

7. Installation category: Class III. If the contactor is manufactured according to the humid tropical conditions, it is allowed to work in places where mold and condensation are present when the relative humidity is not more than 95% (+35°C).


Main Technical Parameters

The AC contactor is open type. Its structure is that the electromagnetic system of the rack plane layout is at the right, the main contact is in the middle, the auxiliary contact is at the left, and equipped with rotatable stop. The whole arrangement is convenient for monitoring and maintenance.

The magnetic system of the contactor is composed of U-shaped movable-static iron core and coil. The movable and static iron cores are equipped with the buffer device to prolong the product life. DC magnetic system of CJ12-Z is made of thick steel plate, and the coil is double-winding and occupies a normally closed auxiliary contacts.

The main contact of the contactor is single break point series magnetic blowout structure equipped with a longitudinal slit arc extinguishing cover, which has a good arc extinguishing performance.

Auxiliary contacts are double breakpoint bridge type with transparent protective cover.

The wearing parts of the contactor are easy to assemble and disassemble and easy to maintain and repair.
