PURPOSE: An apparatus for displaying an on-state or an off-state of an air circuit breaker is provided to improve the operational reliability by simplifying a structure of a display unit. CONSTITUTION: An apparatus for displaying an on-state or an off-state of an air circuit breaker includes a link section(100), a push bar(101), a switch(103), an L-shaped lever(104), and a spring(105). The link section(100) is combined with an operating shaft(2). The push bar(101) is combined with one side of an upper side of the link section. The switch(103) is fixed on an upper end of a frame. The L-shaped lever(104) is selectively connected to an end part of the push bar in order to operate the switch. The spring(105) is installed at one end of the L-shaped lever in order to recover the L-shaped lever.
