ABB 2CSA275901R9105 S-ARC1 M B10 1P+N 10kA Arc Fault Detection Device (AFDD)

Rated 10 A with a Type B tripping characteristic, the ABB 2CSA275901R9105 S-ARC1 M B10 is a 1P+N arc fault detection device with an integrated miniature circuit breaker, giving 10 kA breaking capacity to IEC 60898-1 in a two-module DIN-rail enclosure that also covers overload and short-circuit protection, the M-series step up in fault-current rating over the base S-ARC1 B10 line.

Selection Notes

With a 10 kA rated short-circuit capacity and 10 kA Icu, this M-series device covers boards with higher prospective fault current than the base S-ARC1 can handle at the same 10 A, Type B rating. The B-curve instantaneous trip (3-5x In) keeps it suited to resistive and lighting circuits rather than inrush-heavy loads. Use the 10 A rating where the branch conductor and load match it; the M, B-curve siblings from 6 A up to 20 A scale the same 10 kA fault-current coverage to other branch sizes.
