ABB 2CSA255901R9064 S-ARC1 C6 1P+N 6kA Arc Fault Detection Device (AFDD)

Combining a 6 A Type C miniature circuit breaker with arc fault detection, the ABB 2CSA255901R9064 S-ARC1 C6 is a 1P+N, two-module DIN-rail device rated 6 kA breaking capacity under IEC 60898-1, protecting circuits against overload, short-circuit, series arc faults and parallel arc faults, the lowest-current option in the base C-curve line.

Selection Notes

At 6 A, the Type C trip band (5-10x In) is sized for light branch circuits that still carry enough inrush, such as small pumps or control transformers, to warrant a C-curve over a B-curve device. Use the 6 A rating only where the connected load and conductor are this light; the 10 A and higher C-curve siblings serve heavier branches on the same board. Its 6 kA rated short-circuit capacity covers standard TN/TT final circuits, while the 10 kA S-ARC1 M C6 is available for higher fault-level boards.
