Improvements to a rating plug for an electronic trip unit of a circuit breaker are disclosed. The rating plug includes a non-volatile memory which has access to current and frame rating information. A microcomputer in the electronic trip unit may receive new current rating information over the World Wide Web from a vendor system to update the current rating information of the rating plug. A program within the circuit breaker may detect errors in the new current rating information and may reject such and revert to a safe mode of operation. A billing system may be connected to the vendor system for calculating charges based on the transmission of the new current rating information. Preferably, the non-volatile memory of the rating plug is programmed at the factory site and a label adhered to the outer case of the rating plug for indicating the current rating. The rating plug may then be inserted within the electronic circuit breaker at the field and the current rating altered as necessary using the remote altering system.

World wide web enabled and digital rating plug

A method and apparatus for rejection of an inappropriate rating plug in an electronic trip unit for a circuit breaker including: a microprocessor programmed to determine an overcurrent condition of the circuit breaker; a nonvolatile memory in operable communication with the microprocessor; the rating plug releasably engaged with the microprocessor, the rating plug includes an identification register; wherein the microprocessor reads the identification register, the identification register includes an identification number; wherein the microprocessor accesses one of a plurality of programs in the nonvolatile memory based on the identification number; and wherein the one of a plurality of programs instructs said microprocessor to perform a validation of said rating plug for operation with said microprocessor.

Digital rating plug for electronic trip unit in circuit breakers

A carrier assembly for a surge protection assembly includes: a connector strip; a plurality of pins extending from the connFiguresector strip; and wherein the connector strip and the plurality of pins are formed from a single piece of conductive material.
