Abstract
A single pole circuit breaker comprising a single section. The single section, single pole comprises an electromagnetic sensing device and a pair of relatively movable contacts. The electromagnetic sensing device is electrically connected at one end to the load terminal. The movable contacts are engageable with a pair of stationary contacts carried by a line terminal. A metering or calibrating shunt device is connected on one side to the electromagnetic sensing device and is connected on the other side to the pair of movable contacts to thereby connect in electrical series the electromagnetic sensing device and the pair of movable contacts through the metering or calibrated shunt device. A volt meter connected across the calibration points of the metering or calibrated shunt device will then read a voltage proportional to the current flow through the circuit breaker.
