摘要： A remote actuator for an enclosed molded case circuit breaker utilizes an actuator cable connection with the circuit breaker operating handle in a "pull-pull" arrangement. The cable is arranged in an endless loop between the actuator handle and the circuit breaker operating handle. Moving the actuator handle in a first direction pulls the circuit breaker operating handle to its ON position while moving the actuator handle in an opposite direction pulls the circuit breaker operating handle to its OFF position.

摘要： An industrial rated molded case circuit breaker fitted with an exhaust arc gas manifold arranged over ventilation slots of the circuit breaker and disposed at a line end thereof to redirect the arc exhaust gases exiting the ventilation slots. The exhaust arc gas manifold is fixedly attached to the circuit breaker to prevent an electric fault from occurring between the different phases of a multi-phase electric power distribution system connected to the line end of the circuit breaker. An electric fault is further prevented between the exiting arc gases and the line terminals attached to the circuit breaker thereof.

摘要： A wire cable attachment adapter unit is secured to the top or bottom ends of a circuit breaker or electric switch enclosure to provide strain relief to the electrical power distribution cables that connect with the circuit breakers or switches arranged within the enclosure. The cable support adapter includes a plurality of integrally-formed bulkheads projecting from a support base with upstanding side arms having serrated outer surfaces and separately formed U-shaped clamps having striations formed on the inner legs thereof. The U-shaped clamps are positioned over the side arms to form a cable-receiving channel. After electrical connections are made within the enclosure, the U-shaped clamps are forced against the side arms to fixedly trap the cables within the chamber.

摘要： A remote actuator for an enclosed molded case circuit breaker or disconnect switch utilizes an actuator cable connection with the circuit breaker operating handle in a "pull-pull" arrangement. The cable is arranged in an endless loop between the actuator handle and the circuit breaker operating handle. Moving the actuator handle in a first direction pulls the circuit breaker operating handle to its ON position while moving the actuator handle in an opposite direction pulls the circuit breaker operating handle to its OFF positoin. A retractable handle extender on the actuator handle increases the torquing force applied to the actuator handle and the circuit breaker operating handle.

摘要： A fast operating disconnect switch minimizes the arc that occurs when the switch contacts are opened or closed by operation of a rotor assembly while the switch is electrically energized. A powerful operating spring within the operating mechanism under the control of a handle operator assembly overcenters upon the ON-OFF as well as OFF-ON movement of the handle operator. The handle operator assembly is adapted for either left-hand or right-hand mounting to a common rotor assembly.
