    摘要: A first trip unit for interconnection with a second trip unit includes current transformers and potential transformers for sensing current, voltage and frequency conditions of a circuit breaker's separable contacts. A microprocessor-based trip mechanism provides a trip signal, which is employed by the circuit breaker's operating mechanism to open the separable contacts as a function of the sensed electrical conditions and related predetermined operating values. The microcomputer's transceiver communicates with the second trip unit over a passive two-wire communication cable to acquire the predetermined settings of the second trip unit. The microcomputer includes a firmware routine which employs the acquired predetermined settings as its predetermined values.

    摘要: A circuit interrupter includes a microcomputer-based trip unit, and a display and control panel comprising a numeric display device and a plurality of legends associated with light-emitting diodes. The trip unit presents a sequential display of numeric values of associated circuit electrical parameters and time-current trip characteristic setting values, with the currently visible numeric quantity being identified by an energized light emitting diode and associated legend. The control panel also includes a test switch for initiating a test operation and a potentiometer for selecting a desired simulated fault current value for the test operation. The test capability is provided simultaneously with normal circuit breaker operation which maintains full protection of the associated circuit. A short-delay feature is provided having a selectable i.sup.2 t characteristic with adjustment of both pick-up and time parameters.

    摘要: A circuit interrupter includes a microprocessor-based trip unit, a numeric display, and a plurality of potentiometers each associated with one parameter of the time-current trip characteristic of the circuit interrupter. The trip unit provides a sequential display of the present setting values of the time-current trip characteristic parameters. Adjustment of any of the potentiometers is operable to interrupt the sequential display and to cause the present setting of the parameter associated with the adjusted potentiometer to be displayed. Adjustment of the potentiometer to either limit of its travel causes the most conservative setting value for that parameter to be selected. A hysteresis feature is provided to require a significant adjustment of the potentiometer before a different parameter setting will be selected.Although the potentiometers are continuously variable, operator adjustment thereof results in the selection of one of eight predetermined discrete values stored in the trip unit.

The remote indicating unit also includes relays to provide control of external alarm circuitry upon receipt of cause of trip and demand alarm information. The remote indicator unit further includes a power supply for supplying operating power to the remote indicator unit and to the trip unit. The power supply is powered both from an external AC line connection and from internal rechargeable batteries.

    摘要: A circuit breaker includes a microprocessor-based trip unit and a designator circuit including a plurality of jumper positions. Each jumper position corresponds to one digit of a four digit style number specifying which of a plurality of optional functions and features are incorporated in the specific trip unit. Each jumper position is a multitap voltage divider. Selection of one tap on each of the jumper positions causes a set of four analog voltages to be supplied to the trip unit. An analog-to-digital converter converts the analog voltages to a series of digital representations which are interpreted by the microcomputer as a style number used to command execution of a discrete set of instruction groups, with each instruction group corresponding to one of the optional functions and features.
