A two pole circuit breaker having arc fault and ground fault protection circuits, in addition to a standard thermal-magnetic trip units, that is designed to fit in a standard knock-out, three-quarter inch or one-inch, of a circuit breaker load center panel. The circuit breaker is divided into three compartments with two side-by-side compartments housing the electro-magnetic trip mechanism respectively for each pole, and a third compartment in tandem with the other two for housing the electronics associated with the ground fault and arc fault protection circuits. The circuit breaker spans the area allocated to a single knock-out with portions of the electro-magnetic trip compartments seated within the knock-out opening and with the third compartment hidden behind the panel.
