PROBLEM TO BE SOLVED: To provide an alarm output device which can flexibly cope with any of the inner and the outer attached switches attached to a circuit breaker by a sheet of plate, by improving the shape and supporting structure of an alarm output plate. SOLUTION: The alarm output device outputs a mechanical alarm signal to an attached alarm switch interlocked with a tripping action of the circuit breaker, and makes the attached alarm switch to carry out switching action through an alarm output plate 7 assembled into an opening and closing mechanism 3. The alarm output plate 7 is formed into a shape having fork-shape leg pieces 7a, 7b extending toward the internal alarm switch 5 and the external alarm switch 6 with its tip part as a rocking fulcrum P, and operating end parts 7a-1, 7b-1 of projection shape, individually correspond to the internal and external alarm switches, are provided at the tip part of each leg piece. The rocking fulcrum is axially supported with a pivot 3g of the opening and closing mechanism, and an offset position Q offset from the fulcrum is directly insertion engaged and installed detachably with a toggle shaft of a latch which is interlocked with the releasing action of the opening and closing mechanism.
