ABB 2CSA275103R1104 DS-ARC1 M C10 A30 1P+N Arc Fault Detection Device (AFDD)

The ABB 2CSA275103R1104 DS-ARC1 M C10 A30 is a 1P+N arc fault detection device with an integrated RCBO, combining protection against series, parallel and earth arc faults with overload, short-circuit and 30 mA Type A residual current protection in a single 3-module DIN-rail device. It switches 10 A at 230-240 V AC and carries a 10 kA ultimate breaking capacity.

Selection Notes

The C tripping curve on the 2CSA275103R1104 gives a 5-10x In instantaneous threshold, suited to circuits with contactors, ballasts or small motor loads where a B curve would nuisance-trip on inrush. At 10 A this is the lowest rating in the DS-ARC1 M C-curve line-up: pick the 13 A, 16 A or 20 A version instead when the downstream cable or load is dimensioned for a higher continuous current. Combining AFDD, RCBO and 30 mA Type A residual protection in 3 modules saves panel space versus wiring a separate MCB, RCCB and AFDD module.
