China Offer Power Safety Molded Case MCCB 4p 630A The Mini Circuit DC Breaker
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
