A circuit interrupter arrangement for interrupting current in a circuit path includes a hysteresis control circuit arranged to control a power supply charge-accumulation switch and an undervoltage trip-lockout circuit in parallel. More specifically, the arrangement includes a current inducer circuit for inducing a current signal having a magnitude corresponding to the current in the circuit path; an energy accumulator for accumulating a magnitude of energy to cause an interruption of the circuit path; an energy accumulator control circuit controlling the magnitude of energy accumulating; a trip lock-out circuit, responsive to an insufficient magnitude of accumulated energy, for preventing an interruption of the circuit path; and a range control circuit, responsive to the current inducer circuit, for operating a power-related signal between a first level and a second level to control the energy accumulator control circuit and the trip lock-out circuit.
