Shunt Trip Breaker TRMF2-125T Molded Case Circuit Breaker MCCB 125Frame/3P 15A up to 125A

Shunt Trip Breaker TRMF2-125T MCCB 125Frame/3P 15A up to 125

A shunt-trip breaker, in addition to the internal instantaneous overcurrent and time-overcurrent protective functions, has an externally powered solenoid that will trip the breaker when energized. This is normally tied to a safety interlock system that will shut power off to the affected equipment when, for example, a protective cover is opened or removed. A limit switch or other similar device will be used to detect if the cover is in place or not. It is held open by the cover. If the switch closes, the breaker is tripped and the machine is rendered electrically safe.

TRM series MCCB(Standard use environment for TRM series MCCB)

TRM series 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;

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;
