Abstract
A circuit interrupter including a multipole circuit breaker and a multipole current-limiting reactor device. The multipole current-limiting reactor device includes an insulating housing forming a plurality of compartments, each compartment having a double-wound solenoid connected in series with one pole of the circuit breaker. The current-limiting reactor device limits the current through the circuit interrupter during overcurrent conditions to a value which can be safely interrupted by the circuit breaker.
