Abstract
A solenoid trip unit is electrically connected in parallel with a current limiting polymer element in series with circuit breaker contacts to function as a shunt resistance for the polymer element, becoming energized by transition of the polymer element to its high resistive state, for tripping the breaker contacts open upon such transition. The solenoid may be particularly wound with a resistive wire.
