A circuit breaker includes separable contacts, an operating mechanism to open and close the contacts, and a trip unit cooperating with the operating mechanism to trip open the contacts. The trip unit includes a first component having a processor and a first memory storing a first set of a plurality of trip unit settings, and a second component of the trip unit. The second component is separable from the first component or the trip unit, and includes a second memory storing a second set of a plurality of trip unit settings. The second component saves the first set of the plurality of trip unit settings as the second set of the plurality of trip unit settings in the second memory, and restores the second set of the plurality of trip unit settings in the first memory of the first component or of another first component of another trip unit.

A trip unit is for a circuit breaker and includes a plurality of capabilities defining one trip unit style selected from a plurality of different trip unit styles. The trip unit includes a processor including a communication interface having a communication protocol; and a communication adapter module including a first communication interface having the communication protocol, and a second communication interface. The communication adapter module is structured to learn the plurality of capabilities of the trip unit from the processor employing the communication protocol, and to communicate with any of the plurality of different trip unit styles including the one trip unit style.
