ABB 2CSA275103R1105 DS-ARC1 M B10 A30 1P+N 10A 10kA Arc Fault Detection Device (AFDD)

The ABB 2CSA275103R1105 is a DS-ARC1 M B10 A30 arc fault detection device with integrated RCBO, rated 1P+N, 10 A, curve B, 30 mA Type A residual current and 10 kA breaking capacity. In three DIN-rail modules it combines overcurrent, short-circuit, earth-fault and series/parallel arc-fault protection for one final circuit.

Selection Notes

The M suffix marks the higher breaking-capacity build: 10 kA Icu and 7.5 kA Ics against 7.5 kA Icu and 6 kA Ics on the standard DS-ARC1 B10 A30, so specify this version where the prospective short-circuit current at the installation point is closer to a distribution transformer or main switchboard. The B curve's 3-to-5 times In trip band still assumes a resistive, low-inrush load; a 10 A circuit with motor or transformer inrush needs the C-curve equivalent instead. Within the M line, higher-current circuits move up to the 13 or 20 A version.
