Abstract
A circuit breaker characterized by its ability to qualify for controlling high electrical capacity in a concise configuration employing two sets of contacts separated by a dielectric barrier having anti-arcing features to minimize arcing in a minimal size circuit breaker. Control of the contact movement is through a pivoted actuator and over-center linkage in conjunction with a bell crank lever operating a spring mounted contact moving through a short radius.
