ABB 2CSR256140R1134 RCBO 4-pin

FI/LS-switches (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. They ensure protection of three single-phase or three-phase circuits against overload and short-circuit currents, protection for sinusoidal alternating currents and pulsating currents with smooth DC fault current of up to 6 mA against earth. As well as fault protection (protection against indirect contact), additional protection (with IΔn ≤ 30 mA) and fire protection (with I∆n ≤ 300 mA). They comply with the product standard IEC/EN 61009-1 (VDE 0664-20). Applications include domestic, commercial and industrial applications. The extensive range of accessories offers you everything was needed for your installation tasks. Numerous approvals make the DS203NC fit for worldwide use. Rated switching capacity ICN = 6,000 A according to IEC/EN 61009-1 (VDE 0664-20) for RCDs (residual current protective devices) in residential and similar applications, ICU = 10 kA according to IEC/EN 60947-2 (VDE 0660-101) for MCBs (LS) in industrial applications. RCBO DS203NC A type A is 3polig protected (LS), 4polig switching and can be used in three-phase networks with or without N-conductor.
