Abstract
In an electrical distribution system for controlling current paths through a plurality of associated circuit breakers, a programmable circuit arrangement operates the circuit breakers by remote control in at least the open and closed circuit positions. The circuit arrangement includes a termination circuit for receiving different kinds of remote control signals, each of which is associated with one of the circuit breakers for commanding that each of the circuit breakers open or close its associated current path. The arrangement also includes a programmable controller, which responds to each of the different kinds of remote control signals and to a user-defined program indicating the kind of remote control signal which commands the associated circuit breaker, for generating control signals. An interface circuit then responds to the generated control signals by controlling the circuit breakers between the open and closed positions. The programmable controller may also include a display for indicating the status of the circuit breakers locally and/or remotely.
