摘要： An electronic trip unit within a self-contained circuit interrupter utilizes dual electromagnetic trip actuators. One such actuator responds to overcurrent conditions to interrupt the protected circuit up to a predetermined value. The other such actuator interrupts the protected circuit at all overcurrent conditions in excess of the predetermined value.

摘要： A compact circuit breaker containing an electronic trip unit for interrupting overcurrent conditions within a protected circuit is made operable over a wide operating current range by means of current transformers having multiple turn primary windings. The primary windings are selected to provide a constant ampere-turns ratio to the current transformers without changing the size of the secondary winding or the volume of the transformer core.

摘要： An electronic circuit interrupter includes an electronic trip circuit contained within a circuit interrupter enclosure along with an externally accessible rating plug for setting the ampere rating. The rating plug includes keying tabs that fit within corresponding keying slots formed on the top surface of the electronic circuit interrupter enclosure. Interlock is provided between the rating plug and the electric panelboard which includes a plurality of electronic circuit interrupters connected within an industrial power system. Tabs formed on the side walls of the rating plug are trapped under the panelboard face plate to prevent removal of the rating plug without first removing the panelboard face plate.

摘要： Electronic trip units employed within static trip circuit breakers are individually calibrated and automatically adjusted to ensure that the trip transfer characteristics are within specification requirements. A trimming network within the trip unit circuit contains a plurality of parallel resistors each separately connected within the circuit by means of a fusible link. Test input and output values are compared to idealized values that are binary-weighted within a look-up table in the test equipment computer. The percent correction required is determined and the appropriate links are interrupted to provide ideal trip response.

摘要： A circuit breaker enclosure consists of a cover and a case designed for robotic assembly of the circuit breaker components. A current transformer assembly and a printed wire board containing the electronic trip unit circuit are precisely positioned within the case and cover by means of a transitory circuit breaker case support platform. The transitory support platform includes four upstanding posts that pass through openings formed in the circuit breaker case and are received within corresponding openings through the circuit breaker cover. Leads extending from the current transformer assembly within the case become automatically positioned within corresponding openings through the printed wire board by means of tapered lead-in openings formed within the circuit breaker cover.

摘要： Miniaturized current sensing transformers are electrically and mechanically attached to the printed wiring board carrying the electronic trip unit circuit within molded case circuit breakers. Electrical contacts extending from the current sensing transformers project through openings in the wiring board to springingly engage metal posts extending from the printed wiring board surface. Notched posts mounted on the current sensing transformers, co-extensive with the contacts, snappingly engage the sides of the printed wiring board for good mechanical support and to maintain alignment between the current transformers on the printed wiring board.

摘要： Raised access flooring utilizing panels having a thick, resilient pad bonded directly to and covering the entire surface of the panel. The pad acts like the backing layer of a conventional floor treatment by absorbing impact and attenuation sound. A reinforced face cloth module having only a face layer and a stabilizing layer covers the pad to protect the pad from wear and to provide an attractive floor treatment. The reinforced face cloth module can be detachable or bonded directly to the pad. Alternatively, hook and loop fasteners can removably affix the pad to the face cloth module.
