CIRCUIT BREAKER FOR OPTIMIZING SPACE ALLOCATION

摘要

A circuit breaker for optimizing space allocation comprises: a first overcurrent protection pole (6), having a first incoming line terminal (25) and a first outgoing line terminal (24), a first contact (10) being connected in series to the first overcurrent protection pole, and the first overcurrent protection pole comprising a first operation mechanism (16); a second overcurrent protection pole (7), having a second incoming line terminal (27) and a second outgoing line terminal (26), a second contact (11) being connected in series to the second overcurrent protection pole, and the second overcurrent protection pole comprising a second operation mechanism (35); and an electric leakage protection device (8), comprising a transformer (17), an electromagnetic tripping device (18), an electric leakage tripping mechanism (21), and a test loop (22), the test loop having a test button (20) and a test resistor (19) connected in series, one end of the test loop being connected in parallel with the first incoming line terminal (25), and the other end of the test loop being connected in parallel with the second outgoing line terminal (26). Upon detecting a leakage current, the transformer enables the electromagnetic tripping device to act, and the electric leakage tripping mechanism trips the first operation mechanism and the second operation mechanism, so that the first contact and the second contact are disconnected, thereby implementing the electric leakage protection.
