ABSTRACT:
A driving apparatus for electric power circuit breakers is disclosed which has a substantially rectangular two-part housing. One part of the housing serves to support and hold the drive parts, among which especially shafts, springs, levers and similar parts are to be counted. This part of the housing has a rectangular basic shape in the form of a tray and is designed as a small, light supporting housing part. In the driving apparatus according to the invention, the cover function is assumed by a light plastic part, which functions as protection for the drive parts and therefore is very light.
