TRANER Thermal Magnetic Shunt Trip Breaker TREF2-125/3P 15-125A

TRANER Thermal Magnetic Shunt Trip Breaker TREF2-125/3P 15-125A 

ELCB TREM Series

Mould Case Circuit Breaker with Earth Leakage Protection

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.

Standard
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;

TRM series MCCB(Standard use environment for TRM series 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
