ITEM NAME:   CIRCUIT BREAKER
DEFINITION:  A device with means other than fuses for automatically opening the
             circuit in which it is installed when the current varies from the
             predetermined value for which the device is set. May include
             provisions for manual operation. At least one set of contacts must be
             in series with the actuating element(s). A combination of
             semiconductor and passive devices may be used in lieu of contacts. For
             automatically operated items in which the actuating (tripping) element
             and contacts are not in series, see RELAY (as modified). For items
             which are operated both manually and automatically but the actuating
             elements and contact are not in series, see RELAY-SWITCH. Excludes
             CIRCUIT BREAKER BOX and magneto "breaker" assemblies. See also SWITCH
             (as modified); and CONTROLLER.
