<p>In a control circuit connecting apparatus for a drawer type circuit breaker (101), the position of a main circuit terminal (12) of a circuit breaker body (11) is set to a testing position and then to a disconnecting position in accordance with an amount of drawing out from a drawer frame (21) from a connecting position in which the main circuit terminal is in contact with a main circuit conductor on distribution line side (22). In the connecting position and the testing position, the control circuit connecting apparatus for the drawer type circuit breaker electrically conducts a connector (13L, 13R) of a housing (13) being in an electrically connected state, a normally closed auxiliary contact (15) of the circuit breaker body holding a conductive state when a main circuit contact is open through a contact (23L, 23R) of a terminal block (23), and an electric circuit provided outside the circuit breaker body. A switch (31) is installed in a vicinity of a terminal of the terminal block to which the electric circuit is connected, the switch being adapted to electrically conduct at the disconnecting position in which the connector and the contact are in an electrically disconnected state, to thereby maintain a function of the electric circuit.</p> |
