CJ19 series capacitor changeover contactor

CJ19 series capacitor changeover contactor (hereinafter referred to as the contactor) is mainly used in the electric power circuits with the frequency of AC 50Hz (or 60Hz) and the rated working voltage of up to 400V for putting the low-voltage reactive power compensation equipment into operation or cutting off the low-voltage shunt capacitors.The contactor is equipped with the inrush current suppression device, which can effectively reduce the impact of the closing inrush current on capacitors and suppress the over voltage during breaking.

advantage

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

Notes:

1.The number of auxiliary contacts is represented by two digits,of which he tens digit is the logarithm of normally open contacts,and the units digit is the logarithm of normally closed contacts.

2. For AC-6b 400vAT,the rated working currents corresponding to various specification codes are 25(18A)□32(24A)□43(29□50(36A)□63(48A)□95(58A)□125(87A).

Normal working conditions and installation conditions

The ambient air temperature should not exceed +40℃, with the average temperature of no higher than +35℃ within 24 hours.The lower limit of the ambient air temperature should be -5℃: When the highest temperature is +40℃, the relative humidity of the air should not be higher than 50%; A higher relative humidity is allowed at a lower temperature;
