Abrégé
(EN)
An alarm circuit and method of monitoring a circuit protection device are disclosed. The alarm circuit includes a circuit protection device connected in series at an input voltage of a load. The alarm circuit also includes a programmable circuit connected in parallel to the circuit protection device and including an alarm signal. The programmable circuit is programmed to include a plurality of functional states, and at least one functional state corresponds to activation of the alarm signal. The at least one functional state activating the alarm signal corresponds with an interruption condition in the circuit protection device.
