Installation side by the lateral surface for being provided with hook 1a and linking up with 1b of indicating fault auxiliary contact towards breaker A
Face, snapped connection by linking up with 1a and linking up with 1b and breaker A lateral surface, realize that indicating fault aids in
Contact B installation.
With reference to shown in Fig. 1,4,6, the work to the indicating fault auxiliary contact of breaker of the present invention is former
Reason is specifically described.
When breaker A is in normal "on" position, contact supports 5 bullets that back-moving spring 8 is supported by contact
Power acts on, and contact (15,16) closure, shows the normal "on" position of breaker.
(overload when breaker A is in malfunction, be under-voltage), the 3rd poke rod 201 of activation lever 2
By the effect rotate counterclockwise of breaker A operating mechanism, the triggering end arms 21 of activation lever 2 is pushed up to
One extension bar 51 is with the action upwards of moving contact support 5 so that normally open contact (15,16) disconnects, output event
Hinder signal；Meanwhile breaker A operating mechanism pushes the second poke rod 14b of failure drive rod 14, therefore
Barrier drive rod 14 rotates so that the indicating fault face 14a on the indicating fault end 142 of the other end is exposed to event
Hinder the underface of watch window 17, show fault state of circuit breaker.
When breaker A failure is short trouble, while the push pedal of breaker is moved towards X-direction, push pedal
