Abstract

A multi-pole circuit breaker is disclosed which allows selective manual making and breaking of contacts within the breaker and automatic simultaneous breaking of all breaker contacts whenever a current overload condition occurs at any of the poles of the circuit breaker. The selective and automatic breaking function is accomplished by an interlocking trip shoe assembly comprised of a number of trip levers associated, one each, with a pole of the circuit breaker. Each trip lever is cammed by the movement of the movable contact associated with one of the poles in response to an overload condition at this pole to actuate the armatures associated with the other of the poles to open all other breaker contacts. When the circuit breaker switch associated with one of the poles is moved to an "off" position, a camming member is shifted to a cut away portion of the trip lever such that the trip lever is not cammed when the movable contact swings away from the fixed contact. This permits the breaking of the contacts of one pole without breaking of the contacts associated with the other of the poles. The breaker is provided with vent channels for venting arcing gases and a fine mesh screen in front of the vent channels which acts as a flame arrestor to prevent explosions.
