ABB DSX203NCA-C10/0.03 RCD/MCB 6kA 3P+N Type AC 10 30mA 2CSR256192R1104 content_copy

Residual current circuit breakers (RCBOs) offer protection for people and property as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. They guarantee protection of three single-phase or three-phase circuits against overload and short-circuit currents, protection against sinusoidal alternating currents and pulsating currents with a smooth DC residual current component of up to 6 mA against earth. As well as fault protection (protection against indirect contact) and additional protection (with I¿n = 30 mA). They comply with the product standard IEC/EN 61009-1 (VDE 0664-20). Their patented connection terminals with push-in technology ensure simple and safe contact and handling. Conductors of up to 2 x 4 mm² can be connected to the upper push-in terminal on the output side. On the input side, the PSX phase rails can be used for cross-wiring. For feeding, conductor cross-sections of up to 10 mm² can be connected directly to the device via the screw connection terminal in protection class IP20. For better visibility when feeding, the connection opening of the screw terminal is above the flexible terminal for the phase rail. Numerous approvals make the DSX203NC suitable for use in household and commercial applications.
Rated switching capacity Icn = 6,000 A according to IEC/EN 61009-1 (VDE 0664-20) for RCDs (residual current protective devices) in residential buildings.
RCBO DSX203NC A Type A is 3-pole protected (LS), 4-pole switching and can be used in three-phase networks with or without an N conductor.
