示す。 FIG. 1 is an exploded perspective view of an automatic tripping device for a circuit breaker showing an embodiment of this invention, and FIGS. 2 to 4 are sectional views of the circuit breaker as an embodiment of this invention. 2 shows the off state, FIG. 3 shows the closed state, and FIG. 4 shows the on state. FIG. 5 is an exploded perspective view of an automatic tripping device for a circuit breaker showing another embodiment of this invention. Figures 6 to 8 are cross-sectional views of conventional circuit breakers, with Figure 6 in the OFF state and Figure 7 in the OFF state.
The figure shows the on state, and FIG. 8 shows the trip state. In the figure, 2 is a fixed contact conductor;
a is a fixed contact, 3 is a movable contact conductor, 3a is a movable contact, 3c and 3d are engaging parts, 10 is an opening/closing mechanism, 20
18 is an automatic tripping device, 18 and 19 are sliding members, and 18 is a sliding member.
a and 19a are inclined surfaces. Note that the same reference numerals in each figure indicate the same or corresponding parts.
