ERCO three-circuit track made of aluminium, alternatively DALI controllable This track system made of powder-coated aluminium is the basis for a three-circuit lighting system. It offers two options for operation: as a conventional three-circuit track with three separately switchable circuits, 16 A each, or as a DALI track with one circuit, 16 A and two conductors for connection to the DALI data line - Mounting surface with easy-to-push-out punched holes (spacing 40 cm) - Four insulated copper conductors and pressed-in protective earth - Approval to IEC 60570 (EN 60570/VDE 0711 Part 300)
