Abstract
A moving contact-carrying carriage (8) for an electrical cut-off device which comprises several seats (80) arranged for receiving several parallel moving contacts (5A-5C) offset in space, and each of them is associated with a return mechanism (65). The carriage can be coupled with an actuator mechanism (6) of the device. The carriage (8) comprises an insulating support (81) which has parallel seats (80) and a supporting structure (9), surrounding the insulating support (81), for forming a load-absorbing belt therearound. In order to couple the carriage (8) with the actuator mechanism, the supporting structure (9) comprises a connecting part (91) positioned in a front section of the insulating support (81) and passing through the central seat (80) and resting against the central moving contact (5A), on a side opposite to the return mechanism (65), for directly transmitting driving efforts of the actuator mechanism when opening the electrical circuit.
