Alarm contact (AL)
The alarm contact is used to send signal in case of overload, short circuit, undervoltage or free release.
Terminals AL92 and AL91 are connected when the circuit breaker is open; terminals AL94 and AL91
are disconnected when the circuit breaker is closed; terminals AL92 and AL91 are disconnected and
terminals AL94 and AL91 are connected when the circuit breaker is in release status.
In remote control system, the DI module of PLC can receive the electrical signal sent by the alarm
contact of circuit breaker so that the PLC can detect the fault in the circuit in time. The fault signal can
be transmitted to the screen at the operation station in the control room through the communication
module of the PLC so that the operator can learn the release information of the circuit breaker.
Reasons for alarm contact to send fault indication signal:
Overload
Short circuit
Undervoltage
Manual free release
