Drawer-type circuit breaker

摘要

In the drawer-type circuit breaker, a circuit breaker (1) can be drawn out of a drawer frame (2) by turning a manipulation handle (4). An indicator link (40) moves interlocking with a first link (15B) interlocking with a movable conductor (15), and indicates an ON/OFF in a display section (40b). An interlock liner rod (44) one end of which is formed substantially in a Z-shape and inserted into an aperture (40g) of the indicator link (40) to be link-connected, moves in a longitudinal direction thereof. An interlock lever (46) to which the other end (44a) of the interlock liner rod (44) is link-connected turns round a pin (46a). An abutment portion (46c) of the interlock lever (46) comes in contact with an abutment portion (56a) of a handle lock pin (56) when the movable conductor (15) is at an ON state thereby preventing the manipulation handle (4) from insertion.
