    摘要: A circuit interrupter includes a first terminal, a second terminal, separable contacts moveable between a closed position and an open position, the first and second terminals being electrically disconnected from each other when the separable contacts are in the open position, a printed circuit board Rogowski coil structured to sense a current flowing between the first and second terminals, a current transformer structured to harvest power from the current flowing between the first and second terminals, an electronic trip unit including an other trip circuit structured to output a first trip signal to control the actuator to cooperate with an operating mechanism to trip open the separable contacts based on the current sensed by the current sensor and a thermal trip assembly structured to sense a temperature of a busbar and to output a second trip signal based on the sensed temperature.
