ABB 2CSA275901R9064 S-ARC1 M C6 1P+N 10kA Arc Fault Detection Device (AFDD)

The ABB 2CSA275901R9064 is an S-ARC1 M C6 arc fault detection device with an integrated miniature circuit breaker, combining AFDD protection with 1P+N overcurrent and short-circuit protection in a single 2-module DIN-rail device. Rated for 6 A at 230-240 V AC with a 10 kA ultimate breaking capacity, it detects series, parallel and earth arc faults in addition to standard overload and short-circuit events.

Selection Notes

The C tripping characteristic sets the instantaneous trip threshold at 5-10x In, matching the 6 A rating to lighting and socket-outlet circuits that carry moderate inrush rather than the tighter B-curve window. Combining the AFDD function with the MCB in two modules saves panel space compared with a stand-alone AFDD plus a separate 2-module MCB on the same rail. Where the branch circuit draws more or less than 6 A, pick the S-ARC1 M C variant matched to that design current rather than oversizing this one.
