Applicable scope
CJ20 series AC contactor is mainly used for 50Hz (or 60Hz), rated working voltage to 660V (or 1140V) rated current to 630A power system for long-distance frequent switching and breaking circuit, and with the appropriate thermal relay Or electronic protection devices into electromagnetic starters to protect the circuit may occur overload.
Products meet GB14048.4 and IEC60947-4-1 and other standards
Normal working conditions and installation conditions
Installation of the altitude of not more than 2000m;
The ambient air temperature does not exceed +40 ℃, and the average temperature within 24 hours does not exceed +35 ℃; ambient air temperature lower limit of -5 ℃;
The relative humidity of the installation site does not exceed 50% at a maximum temperature of + 40 ° C; a higher relative humidity may be allowed at a lower temperature, for example 90% at 20 ° C. Special measures shall be taken for the occasional condensation due to the temperature change; the inclination of the contact surface with the vertical surface shall not exceed ± 5 °; the inclination of the contactor mounting surface and the vertical surface of the mineral starter shall not exceed ± 15 °
Pollution level: Level 3.
In the absence of significant shaking, shock and vibration.

Structural features
CJ20 series AC contactor for the double break point direct structure, is installed three-dimensional layout. 40A below the level of "E" -shaped core, 63A below the level of "U" -shaped core, moving bridge for the boat-shaped, static contact with profiles, and equipped with iron arc angle.AC contactor (CJ20 series) is a suitable for long-distance frequent connection and breaking off the main circuit and large-capacity control circuit of the electrical appliances. It is used primarily to control the start, stop, reverse, speed and control of AC induction motors and to combine thermal relays or other suitable protection devices to protect overload or phase off of the motor. It can also be used to control other electrical loads such as electric Equipment, electrical lighting, welding machines, capacitors and so on.
