Abstract:
A current limiting circuit breaker includes two parallel pivoting contact arms carrying contacts at the ends thereof. The upper arm is double pivoted and is operated by a mechanism between open and closed positions. A magnetic drive slot motor device surrounds the lower arm and operates during extreme overcurrent conditions to draw the lower arm down and aid in rapidly separating the contacts. An arm positioning assembly is spring loaded to bias the lower arm toward a closed circuit position and provide contact closing force, the upper limit of travel being set by a rod extending through the end of the lower contact arm to abut against the slot motor.
