Abstract

The circuit breakers involved are of the type having a contact arm pivoted between its ends and operable by a manually erected toggle for closing the contacts. A bell-crank, pivoted to one end of the contact arm, has a latch arm restrained by an over-current latch also carried by the contact arm. That type of circuit breaker is given increased interrupting capability by modification of its component parts, especially the handle and the linkage operated by the handle, to produce greatly increased contact separation.
