  • Patent number: 8081491
    Abstract: A highly accurate current sensing transformer, such as an external neutral current transformer (ENCT), accommodates a wide range of loads. The ENCT includes a housing, first and second terminals each having an end portion extending from and external to the housing, a conductor for carrying a current to be measured, and a current sensor having an aperture for receiving the conductor and having a central axis. The conductor joins the first and second terminals to form a current path that passes through the aperture. Increased accuracy is achieved by arranging the conductor such that a portion thereof passing through the aperture forms a substantial angle relative to the central axis, such that the entry angle of the current path via the conductor through the aperture of the current sensor of the ENCT matches an entry angle of a conductor through an aperture of a current sensor in the electronic trip unit to which the ENCT is attached.

  • Patent number: 7592888
    Abstract: 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.
