摘要：
A circuit breaker trip unit enclosure is adapted to receive rotary knobs that are limited in rotation in proportion to the circuit breaker short circuit rating. The externally-accessible rotary knobs extend within the enclosure to contact with a potentiometer affixed to the circuit breaker trip unit printed circuit board. A stop member is inserted within the enclosure access opening to detent the rotary knob shank that extends through the access opening.
