Adjustment arrangement for a power circuit breaker (power switch) which can be pushed into a withdrawable rack using push-in technology

摘要

In order to achieve disturbance-free coupling of the connecting tab (9) in the equipment rack (5) to the contract surfaces (19) of the sprung contact links (11) of the withdrawable rack (1), it is necessary that the contact surfaces are aligned with one another. This is achieved according to the invention in that the equipment rack (5) has centring pins (23) which project on the rear side (21) and can be inserted without play into adjustable-height centring elements on the withdrawable rack (1) when the equipment rack (5) is pushed into the final position. As a result of the capability to adjust the centring elements, tolerances resulting from production are also compensated for in a very simple manner. <IMAGE>
