A disconnect (break) contact arrangement has disconnect contact blocks which are arranged between two support bars which are common to the disconnect contact block for one pole of the switchgear. Inner clamping pieces seize projections of the disconnect contact block, while outer clamping pieces serve for fastening a conductor section engaging the disconnect contact blocks. If two or more disconnect contact blocks per terminal of a switchgear are required, these are arranged likewise between two support bars and fastened by appropriately designed clamping pieces. In the space between the support bars, insulating spacers serve as additional support.

Disconnect contact arrangement for switchgear movably arranged at guides

A pull-out frame for electric switchgear is provided in the vicinity of its side walls with bolts which serve as pivots or stops of guide rails which can be retrofitted. The guide rails are provided with a keyhole-like opening, the narrower part of which correspond to the diameter of a bolt and the wider part of which correspond to the diameter of the collar of the bolt. The connection of the guide rails to the side walls can be made by shifting the guide rails in the direction of the force of gravity and can be released in the reverse direction. For securing each guide rail in its upright rest position, a latch which extends beyond one leg of the guide rail in fork-fashion is provided which can likewise be retrofitted at the corresponding side wall.
