  • Universal rating plug for electronic trip unit
    Patent number: 8116054
    Abstract: A rating plug for an electronic trip unit is disclosed. The rating plug has a housing with a plurality of switches disposed within the housing, each of the switches positionable in one of two positions. The settings of the switches establish a digital signature associated with the rating plug, providing for a universal rating plug that can be used on any circuit breaker that is accepting of the rating plug and that has a sensor value equal to or greater than the rating plug current rating. For instance, a rating plug having a 1000 Amp rating can be used on any circuit breaker sensor for use at or above 1000 A.

  • CIRCUIT BREAKER TRIP UNIT RATING SELECTION PLUG
    Publication number: 20080158762
    Abstract: A rating plug that, in addition to setting the percentage de-rating on the voltage conditioning (i.e., gain/filter) circuit, by controlling the operational amplifier gain with analog switches in series with the opamp feedback loop, provides breaker frame and/or sensor information to a microprocessor.
