ABSTRACT:
A circuit interrupter protective device characterized by a two-level current limiting structure which provides current limiting on the main or supply side of the current limiter to one level of the peak let through current and to a much lower level on the load side which is achieved by activating a short circuit in parallel with the load by closing a set of shunt contacts the instant the current limiter begins to operate while the current limiter remains in the supply circuit to continue opening the circuit and dissipating the energy of an arc in deion plates.
