    摘要: 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.

    摘要: A circuit protection system for a power panel is disclosed. The circuit protection system includes a transistor connected in a channel of a power panel, the transistor connected between return connections of a load and a return path, and the power panel including a plurality of channels connected to the load. The circuit protection system also includes control circuitry electrically connected in parallel with the transistor, the control circuitry configured to selectively activate the transistor to allow current to pass through the transistor based on an observed voltage across the transistor.
