    Abstract: A circuit interrupter that includes a passive integration channel structured to receive an output signal from a di/dt current sensor and generate a first signal output based on the output signal, and an active integration channel structured to receive the output signal from the di/dt current sensor 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 power supply circuit for a trip unit of a circuit interrupter includes a current transformer, a startup circuit receiving a regulated voltage and a DC/DC converter. The startup circuit is structured to: (i) burden the current transformer with an impedance approximating the trip unit and cause the DC/DC converter to enter the shutdown mode when the regulated voltage is below a predetermined value, (ii) remove the burden and cause the DC/DC converter to exit the shutdown mode and provide power to the trip unit responsive to the regulated voltage reaching the predetermined value, and (iii) remove the burden and cause the DC/DC converter to exit the shutdown mode and provide power to the trip unit responsive to a rate of change of the regulated voltage being at least a predetermined level.
