Abstract

The circuit breaker has a shortened contact separation distance upon manual operation to reduce the stresses imposed upon the breaker operating mechanism when the breaker is manually operated to open or close the contacts. A camming surface is provided on the cradle operator to provide a stop for the toggle pin both upon opening as well as upon closing the contacts. Decreased separation occurs between the contacts upon manual operation. The decreased stresses on the mechanism correspondingly allows for a reduction in the material strength and mass of the breaker flexible connectors, operating springs, and contacts.
