Circuit-breaker section - Coupling section - Outgoing section - Cable chamber - Fuse-switch disconnector section

Technical System Catalogue Ri4Power

Ri4Power Form 1-4 1 Circuit-breaker section For switchgear from all well-known manufacturers such as Siemens, ABB, Mitsubishi, Eaton, Terasaki, Schneider Electric and General Electric. Use of air and moulded case circuit-breakers. 2 Coupling section Combination of a circuit-breaker section with a space- saving, side busbar riser. Reliable separation into individual busbar sections to boost equipment availability. 3 Outgoing section Flexible design of the interior installation. Fully insulated distribution busbars with extensive connection system. For compact circuit-breaker and motor starter com- binations. 4 Cable chamber Available from a field width of 300 mm. Optional cable entry from above or below. Flexible installation with Rittal system accessories. Highest design concordance 4b thanks to optimum terminal compartments. 5 Fuse-switch disconnector section For switchgear from Jean Müller, ABB, Siemens. Alternatively also suitable for installation of equipment modules from Jean Müller. Rittal Technical System Catalogue/Power distribution 2 - 4
