SNC1-20,SNC1-63 AC Contactor - Contactor

Range:
SNC1-20,SNC1-63 AC Contactor(Contactor for short) is mainly designed for AC 50Hz or 60Hz circuits with 230V, rated operating voltage In AC-7a usage, rated operating voltage up to 230V, rated operating current up to 63A, it functions as long distance breaking and circuit controlling. This product is mainly applied to household appliances or low inducatance loading and home electromotor loading control used for the similar purpose.

Normal working and installation conditions:
1. Ambient temperature: -5 to +40℃, the average temperature no more the +35℃ in 24 hours.
2. Aititude: no more than 2,000m.
3. Atmospheric condition: the relative humidity of the installation place should be no more than 50% when the maximum temperature is +40℃ if under a lower temperature, a higher relative humidity is allowed. The monthly average minimum temperature in the wettest month should not exceed +25℃ and the monthly average maximum relative humidity of this month no more than 90%. Besides, the dew on the surface of products caused by temperature change should be taken into consideration.
4. Class of pollution: class 2
5. Installation condition: class 2
6. Installation mode: use the installation orbit of  "Top Cap" seciion TH35-7.5 mould.

Operating Condition:
Under the environmental temperature of -5 to +40℃, puts rated controlling power voltage(Us) on the coil of contactor so as to make it heat to ready state,and the contactor will close under any voltage in the range of 85% to 110%. The voltage releasing will neither than 75%(Us) nor lower than 20%(Us).
