Best Quality 63A 100A 125A 250A 400A 630A 3 Pole MCCB Adjustable Circuit Breaker Molded Case Circuit Breaker
 

Product Description

Standard:
 circuit breaker and auxiliaries comply with the following international standard:
1.IEC/EN 60947-1
Low-voltage switchgear and controlgear-part 1: General rules;
2.IEC/EN 60947-2
Low-voltage switchgear and controlgear-part 2: Circuit breakers;

 MCCB(Standard use environment for  MCCB)
1. Ambient temperature: Within the range of -5ºC--+55ºC(However, when the temperature exceed 40ºC,it should be considered to reduce the capacity to use);
2. Relative humidity: Within the range of 45%--85%;
3. Altitude: 2000m or less(However, if it exceeds 1000m, atmosphere correction through humidity test and withstand voltage test can be considered);
4. Atmosphere where excessive steam, oil steam, smoke, dust, salt and other corrosive materials do not exist;

Classification:
According to the poles:                                          2-poles, 3-poles
According to the rated current:                               Fix type
