Abstract
A circuit protection system includes a plurality of circuit protection devices and a central controller. Each circuit protection device includes a protection switch for connecting or disconnecting a corresponding protected circuit, and a sensing module for sensing electrical parameter data. The central controller is in communication with each of the circuit protection devices, and is constructed to receive the electrical parameter data; determine whether a fault condition has occurred based on the electrical parameter data; and send a signal to open the protection switch for each protected circuit experiencing a fault condition.
