Electrical modular apparatus for assuring differential/disjunction type function, has box with two functional parts, two output connecting units and one input connecting unit whose operation is shared by two functional parts

摘要

The apparatus has a standard unitary width box (B) comprising two functional parts indicated by control levers (1, 2). Two output connecting units (3, 4) corresponds to the two functional parts arranged in the box, in an upper part of the box. The box comprises of an input connecting unit (5) whose operation is shared by the two functional parts.
