    摘要: A unique ground fault circuit interrupting (GFCI) device is utilized to control either an industrial circuit breaker or a contactor in protecting a large power distribution circuit against ground faults. The GFCI device is equipped with plural sets of switch contacts which are actuated incident with tripping of the GFCI device. The particular switch contacts are selected to control energization of an actuator adapted to the circuit breaker or contactor, depending on the actuator type. A ground fault sensor responds to ground faults on the distribution circuit by injecting a current imbalancing signal into the GFCI device, causing it to trip. The consequent switch contact actuation initiates operation of the circuit breaker or contactor to interrupt the distribution circuit.

    摘要: An electrical receptacle assembly affording ground fault protection includes a housing containing fixed contacts supported by socket connector sub-assemblies. A support plate mounts an electronics/magnetics module and operating mechanism sub-assembly including a pivotal, movable contact carrying arm, a latch, a reset button and a trip solenoid. The reset button positions the latch to detain the arm with the contacts in circuit completing relation. On a ground fault, the module effectuates energization of the solenoid to unlatch the arm which moves to separate the contacts.

    摘要: A molded circuit breaker case complete with line and load terminals is fashioned to house a molded case circuit breaker. Rigid conductive straps affixed to the outer case provide electrical connections between the case line and load terminals and the circuit breaker line and load terminals, respectively, and, in addition, serve to secure the circuit breaker in place. The circuit breaker operating handle protrudes through an opening in the outer case to facilitate manual circuit breaker operation.

    摘要: A molded case circuit breaker movable contact arm electrically connects with the circuit breaker load terminal without requiring a flexible electrical conducting braid. The contact arm is pivotally arranged within a contact arm support to which the load terminal lug is attached. The contact arm pivot pin is supported on a pair of parallel support posts extending from the contact arm support and a pair of bifurcated shunt plates are positioned on the pivot pin, one on each side of the contact arm to promote good electric transport between the contact arm and the support posts during short circuit conditions without interfering with the rotational movement of the contact arm.

    摘要: An integrated protection unit is a circuit breaker which includes basic overcurrent protection facility along with selective electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components contained within the integrated protection unit cover from the environment. A combined overcurrent trip actuator and multiple accessory unit can be field-installed within the integrated protection unit. The combined actuator-accessory unit includes electronic control circuitry for the accessories along with mechanical trip and reset interface components. The reset mechanism allows the actuator-accessory unit to become reset without interferring with the operation of the integrated protection unit.

    摘要: A rope holder includes a body having anchoring means facilitating attachment to a member. The free end of a rope leading from an object to be tied down, is threaded through a first aperture and then a second aperture, both formed in the body. Also formed in body is a V-shaped notch having its wide end in open communication with the second aperture. The rope is pulled tight through the two apertures and then moved laterally out of the second aperture into the slot, where it is wedged to maintain the desired rope tightness.
