Description
About the DS-ARC1
About the DS-ARC1
Rated at 20 A, the ABB 2CSA275103R1204 DS-ARC1 M C20 A30 is a 1P+N arc fault detection device with an integrated RCBO, combining a C tripping curve with 30 mA Type A residual current protection and detection of series, parallel and earth arc faults in 3 DIN-rail modules. Operational voltage is 230-240 V AC with a 10 kA ultimate breaking capacity.

Selection Notes
With a 20 A rating, the 2CSA275103R1204 is the highest current member of the DS-ARC1 M C-curve family in this range, intended for circuits whose cable and load exceed what the 16 A or lower variants can carry continuously. The C curve trips instantaneously at 5-10x In, tolerating motor and ballast inrush rather than nuisance-tripping. Because the AFDD, RCBO and 30 mA Type A residual protection are built into the same 3-module housing across every rating, moving up to 20 A does not add panel width.
