CJT1 series AC contactor

CJT1 series AC contactor is mainly used for AC 50Hz (or 60Hz), rated voltage up to 380V, current to 150A power line, for frequent remote connection and disconnection of lines and control of motor, and can be used with appropriate thermal relay Or an electronic protection device is combined into a motor protector to protect circuits that may be overloaded. CJT1 series AC contactors comply with IFC947.GB14048.4 and JB/T8730 standards and are an alternative to CJ10 series contactors.

CJT1 series AC contactor working conditions and installation conditions:

1 Ambient air temperature: -5 ° C ~ +40 ° C, the average value within 24 hours does not exceed +35 ° C.

2 Altitude: no more than 2000m.

3 Atmospheric conditions: When the maximum temperature is +40 °C, the relative humidity of the air does not exceed 50%; at lower temperatures, higher relative humidity can be allowed, for example, 90% at +20 °C, occasionally due to temperature changes Special measures should be taken for the condensation.

4 Pollution level: Level 3.

5 Installation category: Class III.

6 Installation conditions: The inclination of the mounting surface and the vertical plane is not more than ±5°.

7 Shock vibration: The product should be installed and used in places where there is no significant shaking, shock and vibration.

The contactors are divided into 10A, 20A, 40A, 60A, 100A, 150A according to the current level.

The coil rated control power supply voltage Us is: AC (50Hz): 36V, 110V, 127V, 220V, 380V.

Operating conditions: the pull-in voltage is (85%~110%) Us;

The release voltage is (20%~75%) Us.
