The S-ARC1 is the new 1P+N Arc Fault Detection Device (AFDD) with an integrated Miniature Circuit
Breaker (MCB) in only two module width. Besides the overcurrent protection of the MCB, the S-ARC1
provides additional protection against series, parallel and earth arc faults. The series is perfectly in- 3
tegrated with ABB’s System pro M compact® range. Combined with a Residual Current Circuit
Breaker (RCCB) as upstream device, the S-ARC1 provides the best solution for complete protection
of electrical installations in buildings.
