2074268 9210018 PCTABS00013 A solid state circuit interruption arrangement in a distributed power network provides fast and reliable circuit interruption. A common power source (10) provides power to a plurality of loads (12, 14) via respective current paths. A main circuit breaker (16) and a plurality of solid state circuit breakers (18, 20) are arranged to interrupt the current paths in response to command signals sent from a central controller (22). Current sensors (24, 26) and voltage sensors (28, 30) are coupled to the current paths for monitoring purposes. An automatic controller (22) responds to any of the current sensors (24, 26) detecting a fault condition by automatically generating a command signal, which forces the associated solid state breaker (18, 20) to interrupt the associated current path. Thereafter, the controller (22) automatically generates a signal to the main circuit breaker (16) to interrupt the power provided from the common power source (10) in the event that the associated current path is not interrupted by the solid state breaker (18, 20).
