ABSTRACT:
A power switching module is adaptable for installation in a variety of existing circuit breaker panels. The module contains electrical controls providing selected control functions, such as an integral timer function. The module plugs into an existing breaker position in the circuit breaker panel adjacent a conventional circuit breaker on the same panel. The module has external terminals, including an interchangeable clip for connecting to the circuit breaker panel buss, a switched-circuit input series-connected to the load line output from the adjacent circuit breaker, a switched circuit output for carrying power to an external load being controlled by the switch, and a neutral wire extending to a neutral terminal on the panel. A microprocessor contained in the module provides the switched timer function that is set by digital inputs and displayed on the module housing. The microprocessor obtains operating power from the circuit breaker panel buss and controls operation of the switch solenoids. The power switching module obtains power for the switched load and over-current protection from the series-connected circuit breaker.
