Abstract
An electrical assembly, for example for use in low voltage supply distribution, comprises a fixed casing (4) for each of three phases. A pair of fixed contacts (e.g. 11, 12) are spaced apart within the casing and set back from an opening into the casing. A fuse carrier (29) is mounted for rectilinear sliding movement within the casing between a first position adjacent to the opening and a second position. In the second position movable contacts (30, 31) on the carrier engage the fixed contacts to close a circuit therebetween. A drive unit (50) is provided for mechanically driving the carrier between the two positions, the drive unit being a self-contained mechanism comprising a housing and a drive member movable relative thereto. The drive member can be detachably coupled to the contact carrier, and means (58, 60) provided for releasably locking the drive housing to the fixed casing. Thus, the drive unit is a separate entity from the contact assembly and can be used as required to drive any selected contact carrier.
