CJX2-N series interlocking contactor

CX2-N series interlocking contactor is mainly used in the circuits with the frequency of AC 50Hz (or 60Hz), the rated insulation voltage of up to690V, and the rated working current of up to 954A when the rated working voltage is 380V under the use category ofAC-3 for controlling reversibly operating or reversibly braking motors and dual power supply control, and working with the appropriate thermal relay to form the electromagnetic starter to protect the circuits that may be overloaded.Executive standards:GB14048.4 and 1EC60947-4-1.etc.

advantage

All products of the company can be customized for production according to user usage scenarios.

product details

Type and meaning

Normal working conditions and installation conditions

The altitude of the installation site should not exceed 2000m;

The ambient air temperature should not be higher than+40℃ and not be lower than-5℃.

When the highest temperature is +40℃, the relative humidity of the air on the installation site should not be higher than 50%;A higher relative humidity is lowed at a lower temperature:In the wettest month.the monthly average minimum temperature should not exceed +20℃ and the average maximum relative humidity should not exceed 90%. Measures should betaken for condensation on the product due to temperature change.

The inclination between the installation surface and the vertical plane should not exceed ±22. 5~.

Pollution level:level 3;

The product should be installed in a place without obvious shaking, impact and vibration.

Structural features of the product

The action mechanism is of direct acting type, and the contact is of double breakpoints.

With the combination function, all surfaces except for the installation surface may be additionally provided with accessories.

Auxiliary contact sets maybe additionally installed on both sides.

Auxiliary contact sets or air damping, type time relays may be additionally installed on the upper side.

The coil terminal may be additionally provided with various functional modules such as time delay units.

Both mechanical and electrical interlocking can be achieved.
