MCCB TRM2-50/2

TRM2 series circuit breakers and auxiliaries comply with the following international standard:

IEC/EN 60947-1: Low-voltage switchgear and controlgear-Part 1: General rules

IEC/EN 60947-2: Low-voltage switchgear and controlgear-Part 2: Circuit breakers

TRM2 series FRAME.50 MCCB (Standard use environment)
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:
