ABB 2CDR272568R1167 RCBO RCD (all types of current) 2-pin

FI/LS combinations (RCBOs) offer personal and property protection as well as protection against electrically ignited fires according to DIN VDE 0100-410 and DIN VDE 0100-530. The FI/LS combinations of the DS250N-UC series ensure protection against sinusoidal AC currents, pulsating currents against earth and smooth DC fault currents with a wide range of (high/) frequencies, as well as fault protection (protection against indirect contact), additional protection (with I∆n ≤ 30 mA) and fire protection (with I∆n ≤ 300 mA). They meet the product standards for type A DIN EN 61009-1 (VDE 0664-20) Appendix G and type B DIN EN 60947-2 (VDE 0660-101). The DS250N-UC series are special FI/LS combinations for use in the area of direct current commuter trains, especially within the overhead line area. They were developed in accordance with the above product standards and correspond exactly to the recommendations of the VDV font 509 (10/08): "Use of residual current (FI) protective circuits in electrical energy systems of direct current commuter trains". The DS250N-UC consists of an all-current-sensitive FI block (type B) and a LS part of one or three phase conductor poles in AC version as well as two reverse-direction neutral pole in UC version. The switches are completely assembled at the factory.
