Description
Shunt Trip Breaker TREF4-250 Earth Leakage Circuit Breaker ELCB 250F/4P 100A-250A
Type A RCBO
ELCB TREM Series
A Shunt trip breakers are often used in concert with sprinkler and other fire suppression systems that can potentially short-circuit electrical appliances. The shunt breaker is connected to the fire detector or alarm, so that when the alarm is triggered, the breaker is automatically tripped, cutting the power to any computers, electronic locks or other electrical equipment before the sprinklers can soak them in water.

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
