<p>An electronic trip device case for a circuit breaker, an electronic trip device, and an assembling method thereof are provided to measure and process different values showing a current flowing in an electromagnetic operation device and a distribution circuit. A case includes a bottom part(22) and a cover. A first surface and a fist side panel are positioned in the bottom part. A second surface and a second side panel are positioned on the cover. A penetration hole for the operation of the electronic module is formed on the second surface. The second side panel forms a first cavity for receiving the bottom part. The bottom part and the cover form the second cavity for receiving the printed circuit board to a direction in parallel to the second surface. The second cavity includes a sheath(58). The sheath is opened through the connection path and the operation hole of the first side panel. The sheath receives the actuator.</p> |
