Energy validation arrangement for a self-powered circuit breaker

摘要

A circuit interrupter arrangement for interrupting current in a circuit path. The circuit interrupter, including a current inducer circuit; a power supply including a capacitor; a trip command circuit, responsive to a fault in the circuit path; an electrical latch actuated in response to the electrical signal from the trip command circuit; and a control circuit responsive to said at least one current signal provided by the current inducer circuit. The control circuit is arranged for preventing the electrical signal from engaging the latch until after a prescribed minimum period of time.
