Internal Accessories
1. Alam switch(AL)
Alarm switches offer provisions for immediate audio or visual indication of a tripped breaker due to overload, short-circuit, operation of shunt trip, or undervoltage trip conditions, operation of push button. They are particularly useful in automated plants where operators must be signaled about changes in the electrical distribution system. This switch features a closed contact when the circuit breaker is tripped automatically. In other words, this switch does not function when the breaker is operated manually. Its contact is open when the circuit breaker is reset.
2. Auxiliary switch (AX)
Auxiliary switch is for applications requiring remote ""On"" and ""Off"" indication. Each switch contains two contacts having a common connection. One is open and the other closed when the circuit breaker is open, and vice-versa.
3. Shunt trip (SHT)
The shunt trip opens the mechanism in response to an externally applied voltage signal.
