A user adjustment assembly for translating user-adjustable dial settings to tripping levels of an electronic trip unit includes a potentiometer and an adjustment button. The potentiometer is positioned inside a cover of the trip unit and includes a potentiometer button. The adjustment button is coupled to the potentiometer for mechanically adjusting it and includes an insulation disc for increasing resistance to electrostatic discharge, preventing contaminants from entering the printed wire assembly components, and preventing application of downward force to the potentiometer button. The insulation disc has a bottom surface that is dimensioned to be larger than the potentiometer button. The adjustment button includes one or more stops that trigger a fail safe operation mode where the tripping levels are automatically adjusted to higher or predetermined protective levels when the adjustment button is moved to those stop positions. Switch calibration is obviated and the simplified design reduces overall cost. |

A translation technique for translating mechanical button positions of a circuit breaker to trip point settings stored in a memory of the circuit breaker. A turn of a mechanical button turns a potentiometer button, whose output is converted to scaled voltages and converted to corresponding digital values. These digital values are checked against a range of thresholds (minimum/maximum) corresponding to mechanical orientation positions of the mechanical button. Once the mechanical orientation position is determined by scaling and converting the potentiometer output, a trip curve lookup table stored in memory is accessed to determine which trip point setting should be set for the circuit breaker based upon the button position. The circuit breaker's trip curve settings can be changed easily via the mechanical button. They can also be changed easily by modifying the trip curve lookup table without having to recalibrate the circuit breaker or the switch settings. |

The invention relates to a re-settable, single-phase, thermo/electric circuit breaker utilizing a U-shape bimetallic element of substantial resistance properties in the circuit, so that when a predetermined overload current occurs the bimetallic element self heats and moves to trip a mechanism that opens the breaker circuit. The invention replaces the double-contact break configuration normally associated with a breaker of this type, with a single contact break configuration designed to produce a sliding action between contacts during the normal reset operation, providing a more reliable continuity at the moveable and stationary contact interface that is also less expensive to produce. |

A draw out interlock comprises an elongated interlock member which is coupled to the manual trip mechanism of a circuit breaker. The interlock member is springed bias to an extended position where it projects through the back wall of the circuit, but is retained in a retracted position by the surface against which the circuit breaker is mounted. As the circuit breaker is removed from the mounting surface, the interlock member extends actuating the manual trip mechanism and interrupting current before the circuit breaker becomes disconnected from the protected conductor to prevent arcing at the disconnects. |

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. |
