Abstract
A multi-pole group-operated switch configuration is provided for electrical distribution circuits. The switch configuration includes integral arrangements for sensing circuit parameters and supplying power for a switch operator of the switch configuration. The switch configuration includes a plurality of switch-pole units. In accordance with desired characteristics and features, one or more of the switch-pole units includes an integral current-sensing device, an integral voltage-sensing device, or an integral combination voltage and current-sensing device. The voltage-sensing device also provides operating power to power a switch operator and charge the batteries of the switch configuration.
