Abstract: A trip unit (4) is for a circuit breaker (2) 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 (10) including a communication interface (52, 54) having a communication protocol; and a communication adapter module (18) including a first communication interface (55) having the communication protocol, and a second communication interface (70). 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.

Abstract: A circuit interrupter (4) that includes a passive integration channel (32) structured to receive an output signal from a di/dt current sensor (30) and generate a first signal output based on the output signal, and an active integration channel (34) structured to receive the output signal from the di/dt current sensor (30) and generate a second signal output based on the output signal that is proportional to the primary current received by the di/dt current sensor. Circuit protection functionality is provided based on the first signal output responsive to the primary current being determined to be greater than a threshold level, current metering and circuit protection functionality is provided based on the second signal output responsive to the primary current being determined to be less than or equal to the threshold level, and a seed current value is provided to the active integrator based on the first signal output.

Abstract: A circuit interrupter (10) includes an electronic trip unit (40) structured to receive power from a power supply (15). The electronic trip unit includes a start-up process and is structured to proceed through the start-up process when the electronic trip unit begins receiving power from the power supply and a timing circuit (70) including a capacitor (72) structured to begin charging when the electronic trip unit begins receiving power from the power supply. The electronic trip unit includes a processor (60) that is structured to read a voltage across the capacitor when the start-up process has completed and to determine an elapsed time of the start-up process based on the read voltage across the capacitor.
