CJ20 Series AC Contactor
CJ20 series AC contactors are mainly used to connect and disconnect circuits in electrical service systems with AC 50Hz, voltage to 660V(individual grade 1140V) and current to 630A and to form electronic magnetic starters with appropriate thermal relays or electronic protection devices to protect electrical appliances that may be overloaded.
Specification Parameter
*According to 380VAC-3 rated working current is divided into I0,I6, 25,40,63,100,160,250,400,630A ten.
*According to the rated power supply voltage properties of the control loop:
a.AC (50Hz)36, 127, 220, 380V four kinds;
b.DC: 48,110,220V three kinds;
Product Advantage
appropriate thermal relays or electronic protection devices to protect electrical appliances that may be overloaded
1.Amblent air temperature
a. The upper limit of ambient air temperature does not exceed +40℃:b. The lower limit of the ambient air temperature is not less than -5℃ (it can also be -10℃ or -25℃, but it should bestated to the manufacturer when ordering)
2.Altitude
The elevation of the installation site does not exceed 2000m.
3.Atmospheric condition
The relative humidity of the atmosphere does not exceed 50% at the maximum temperature of +40℃. The relative humidity can be higher at lower temperatures, and the monthly average maximum relative humidity can be 9% when the monthly average minimum temperature is +25℃ in the wettest month, and the condensation on the surface of the product due to temperature changes should be considered.
