Abstract:
A circuit interrupter comprises a molded insulating housing molded to form improved vent passage means for venting arc gases from the housing.
Abstract:
A terminal lug is provided for connecting an electric cable to an electric bus conductor in which the terminal lug is held to the electric bus conductor by a U-shaped clip. The terminal lug comprises a body member having a passage formed therein for receiving the electric bus conductor and a portion of the electric cable. A boss is formed in the passage for engaging an opening formed in the bus conductor when the bus conductor is inserted in the passage through the body member. The U-shaped terminal clip holds the bus conductor to a portion of the internal surface of the passage through the body member so that the boss formed in the passage engages the opening in the bus conductor to securely fasten the terminal lug to the bus conductor. A terminal screw extends into the passage through the body member opposite the bus conductor to engage the electric cable and force a portion of the electric cable into good electrical connection with the bus conductor.
Abstract:
A circuit breaker comprises a current responsive tripping bimetal and a pair of compensating bimetals in latching engagement with each other to compensate for movement of the current responsive tripping bimetal in response to changes in ambient temperature. The circuit breaker is a multi-pole circuit breaker with a current responsive tripping bimetal in each pole and one pair of compensating bimetals in only one of the poles.
Abstract:
A circuit interrupter comprises a molded insulating housing molded to form means for insulating mounting bolts from live parts of the circuit interrupter mechanism.
