Trip bar for a multipole breaker block associated with an auxiliary trip block.

摘要

The tripping movement in the side-by-side position of the breaker block 10 and of the auxiliary trip block 12 is transmitted by means of a modular trip bar 26 put together by the transverse fitment of two fingers 44, 52 with the levers 30 for tripping the poles 14, 16. The finger 44 is retained in a housing 66 of the lever 30 belonging to the pole 14 in order to form a first bidirectional mechanical link 47 allowing multipole tripping by transmitting the trip movement of one of the poles 14 to the other pole 16 and vice versa. The finger 52 of the second unidirectional mechanical link 48 co-operates directly with a shoulder 62 of the lever 30 of the other pole 16 adjacent to the trip block 12. <IMAGE>
