These contactors are suitable for controlling 2 separate circuits, i.e. 2 loads with 2 separate supplies, or 1 circuit comprising
2 separate loads with a single supply (see diagrams below). When the contactor operates there is no mechanical overlapping
between the N.O. poles and the N.C. poles: BREAK before MAKE.
