Abstract: Un resorte conductor (102) para ejercer una fuerza de polarizacion contra un boton de prueba (22) para abrir un circuito de prueba de interruptor de circuito (84). El resorte (102) incluye un cantilever alargado de una pieza (104) que tiene un primer extremo (106) y un segundo extremo (110). El cantilever (104) es formado de un material eléctricamente conductor. Uno de los extremos de cantilever (106) está adaptado para sujetarse directamente a una primera terminal (44) del circuito de prueba (84). El otro extremo del cantilever (110) está adaptado para hacer contacto en forma directa y reversible con una segunda terminal (126) del circuito de prueba (84). El resorte (102) también incluye medios para flexionar resilentemente el segundo extremo (110) del cantilever con relacion al primer extremo (106). Los medios de flexion (134) son formados integralmente con el cantilever. También se proporciona un interruptor de circuito de falla de tierra y un modulo de circuito de falla de tierra (84) para proteger un interruptor de circuito con un aditamento de empujar para probar (22).

Abstract: DC101 A charging mechanism for a circuit breaker includes a pair of one way roller bearing clutches that permit incremental charging rotation of a ratchet wheel without requiring a holding pawl. The charging springs are attached by means of planar spring ends that are readily inserted between end turns of the spring and rotated into a locked position. A novel wear pad includes a surface consisting of nylon impregnated molybdenum disulphide for minimal friction contact with a rotating eccentric on an electric charging motor.

Abstract: Se proporciona un modulo de falla de tierra para proteger un interruptor de circuito conectado entre las terminales de carga y de línea de una línea de energía de fase y de neutral, un conductor de fase que tiene un cuerpo rígido, alargado hecho de material solido, conductor eléctrico con extremos primero y segundo está adaptado para conexion a la línea de energía de fase de carga y de línea. Un conductor de neutral que tiene un cuerpo rígido, alargado, hecho de material solido, conductor eléctrico con extremos primero y segundo está adaptado para conexion a la línea de energía de carga y de neutral. De preferencia, se usan terminales para agarrar los extremos de conductores de fase y de neutral a la línea de energía de carga y la línea de neutral de carga. Los conductores de fase y de neutral están conectados operativamente al sensor. La presente invencion también proporciona un conjunto de alojamiento para un interruptor de circuito de falla de tierra que incluye una base hecha de material eléctricamente aislante con una pluralidad de cavidades para retener el modulo de falla de tierra y terminales en ella.

Abstract: DC97 A circuit breaker drawout arrangement includes a drive mechanism for moving a circuit breaker along a pair of rails between a Connect and a Disconnect position by means of a drive tool. A torque limited clutch permits a lower maximum torque when moving the breaker to the Connect position and a greater maximum torque when moving from the Connect position to the Disconnect position. In one embodiment the clutch is formed by a pair of oppositely orientated unidirectional roller clutches in the drive nut and in another by a ball and detent arrangement in the drive nut.

Abstract: The present invention provides a wireway assembly for mounting to the housing wall of an electrical distribution device to enclose and protect electrical wiring therein. Generally rectangular, u-shaped channels have at least one aperture positioned in the channel wall to overlap the aperture of an adjacent channel to define a wireway through which the electrical wiring extends from the bight portion of one channel to the bight portion of the adjacent channel. An interlocking means manually attaches and detaches each channel with an adjacent channel and with the housing wall. The present invention also includes a method of safely protecting electrical wiring extending across a housing wall of an electrical distribution device. The method includes the step of interlocking a plurality of ushaped channels in an abutting position to each other and the housing wall.

Abstract: The invention provides a spring exerting a nonlinear force between a contact carrier and a contact blade in a circuit interrupter. The inventive spring includes at least one elongated cantilever. The length of the cantilever has the shape of an arch made with a non-uniform angle and is formed from an elastic material. The cantilever is supported at one end against the carrier with the length of the cantilever positioned parallel to the carrier and the opposite end of the cantilever abutting the contact blade so that the carrier supports more of the length of the cantilever as the displacement between the carrier and the contact blade decreases. The invention also includes a method of operating a circuit interrupter by non-uniformly increasing the force exerted against a movable contact as it engages a stationary contact to complete a circuit.

Abstract: DC98 A racking mechanism for a fused circuit breaker includes a drive assembly that is removable as a unit from the breaker and fuse truck. The drive assembly includes a drive unit having a drive screw and a travelling nut and yoke for rotating a pair of levering arms for moving the breaker among a plurality of positions in a cubicle. All interlocks are included on the modular drive assembly. An indicator is cam operated by the travelling nut and includes a face having indicia that identifies the direction of rotation of the drive screw.
