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.
