Cj19I Contactor for Capacitor Switching with Opening Design

Product Description

 

Product Description

General
CJ19i contactor for capacitor switching (hereinafter called contactor) is suitable for the circuit of AC 50Hz/60Hz with rated rated voltage up to 690V. It is mainly used to add  low voltage  reactive  power  compensation  equipment  or  cut  off  low  voltage parallel capacitor. The contactor is equipped with a device to suppress the inrush current, which can effectively reduce the impact of the making inrush current on the capacitor and suppress the over-voltage when the capacitor is cut off.
Standard: IEC/EN 60947-4-1.

Operation conditions
Ambient  temperature:-5ºC~+40ºC,  the  average  during  24  hours  should  not exceed +35ºC;
Altitude:≤2000m;
Atmosphere conditions: At mounting site, relative humidity not exceed 50% at the max  temperature  of  +40ºC,higher  relative  humidity  is  allowable  under  lower temperature. For example, RH could be 90% at +20ºC, special measures should be taken to occurrence of condensation;
Pollution degree: 3
Installation category: III
Installation  conditions:  the  inclination  between  installation  plane  and  vertical plane is within ±5°
Impact and shake: the products should locate in the places where there are no obvious impact and shake.
