Signaling device for circuit breaker and electrical apparatus comprising the signaling device

摘要

Signaling device (100) suitable to be operatively coupled to a circuit breaker, comprising: an electrical switch (1) configured to generate an electrical signal indicating a transition from a first state circuit breaker to a second state; a drive mechanism (2) for actuating the electrical switch; a movable body (3) which is pivotally mounted about a first axis (101) to interact with the actuating mechanism; and a return spring (14) is operatively connected to the pivoting body (3) and is installed around an axis substantially parallel to said first axis, and further comprises a suitable transmission mechanism (4) to operatively interact with the circuit breaker for cause a rotation of the pivoting body corresponding to said transition of the circuit breaker from the first state to the second state, characterized in that the transmission mechanism (4) comprises: a pivoting lever (18) provided with a first arm (21) It is pushed by a portion (39) of the circuit breaker, and a second arm (22) to abut against an activating push element (27) of the pivoting body (3) to cause a pivoting configuration in which it rotates; another pivot (19) fixed on said pivoting body around the pivoting lever can rotate; and a return spring (24) causes the pivoting lever to rotate the pivoting lever between an intermediate position assumed under the action of the circuit breaker and an operation to be taken place when the pivoting body is in a rest position.
