CIRCUIT BREAKER WITH COMMON TEST BUTTON FOR SEPARATE TESTING OF GROUND FAULT AND ACR FAULT FUNCTION

摘要

PURPOSE: A circuit breaker with common test button for separate testing of ground fault and ACR fault function is provided to perform radio frequency communication with a communication terminal based on a code modulation system such as the W-CDMA, and to improve the performance of both incoming/outgoing channel signals in the communication station having a reception path. CONSTITUTION: A miniature circuit breaker providing arc fault protection and ground fault protection has a common rocker button that selectively deflects orthogonally oriented flat electrically conductive test switch spring contacts of an arc fault test circuit and a ground fault test circuit into engagement with a common contact to test each of these protection functions independently. The pivot axis of the rocker button is parallel to the planes of each of the test switch spring contacts and the button has opposed fingers which preload both of the spring contacts to bias the rocker button to a neutral position.
