Shunt Trip Breaker TRMF4-250 Mould Case Circuit Breaker MCCB 250F/3P 100A-250A

Shunt Trip Breaker TRMF4-250 Mould Case Circuit Breaker MCCB 250F/3P 100A-250A

Shunt trip breakers are often used in concert with sprinkle 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.
