摘要： A circuit interrupter includes an adjustable trip unit for tripping the circuit breaker to the open circuit position upon overload current conditions. The trip unit includes a shorting plug adjuster comprising a pair of connecting pins electrically connected together and insertable into cooperating sockets in the trip unit housing. One of the pins is common to all adjustment positions and is of greater length, having a retaining clip at the end thereof to permit the adjuster to be partially withdrawn, pivoted about the common pin, and inserted into the desired position. The adjuster comprises a flange which covers the trip unit panel socket in all positions, thereby providing protecting against dust and other contamination. The adjuster is cheaper and more reliable than the prior art, providing increased protection against shock, vibration, and contact bounce.

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.

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.
