Trip unit communication adapter module employing communication protocol to communicate with different trip unit styles, and electrical switching apparatus and communication method employing the same

摘要

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.
