AGuide to the product choice1 - List for Emax 2 selectionForeword The circuit-breaker must check and protect , in case of failure and malfunction, the installation componentsthat are connected to it. To perform this function, Emax 2 circuit-breakers offer a series of options, that canbe selected by the user according to the particular requirements of the installation.For a good design, the main characteristics the components must be selected with the greatest care.In order to help the design engineers in selecting the Emax2 circuit-breakers, a sheet is provided belowcontaining the main selection criteria for air circuit-breakers. This sheet can be completed (in whole or in part)by the design engineer to guide subsequent design choices and can be used by the client for work contracts.Besisdes, this sheet is a useful tool for rapid configuration in CAT selection software.Device Type of deviceCircuit-breakerSwitch-disconnectorStandard Reference standardIEC (EN 60947-2)UL (UL 1066-ANSI C37.50)Mechanical characteristics Insulation functionYesNoNº poles34Installation versionFixedWithdrawableTerminalsHorizontal/VerticalSpreadFrontExtended frontSpread frontFloorFor 4x240 FcCuAl cableNOTE: details of the terminals are given in Emax 2 catalogue available on the website http://new.abb.com/low-voltage/products/circuit-breakers/emax2.
