Why Choose the ABB S-ARC1 M B10 Arc Fault Detection Device?
The ABB S-ARC1 M B10 is a compact arc fault detection device (AFDD) with integrated miniature circuit breaker (MCB) designed to provide enhanced protection for single-phase final circuits. Part of the ABB S-ARC1 M series, it combines arc fault detection with thermal-magnetic overload and short-circuit protection within a single two-module DIN rail device.
The S-ARC1 M is designed to protect end-user single-phase circuits against earth, parallel and series arc faults as well as overloads and short-circuit currents. This allows the device to detect potentially hazardous electrical arcing that conventional MCB protection alone is not designed to identify, helping reduce the risk associated with electrically initiated fires.
With a rated current of 10 A, a B tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 M B10 provides a 7.5 kA rated service short-circuit breaking capacity and a 10 kA rated ultimate short-circuit breaking capacity. Its 1P+N configuration and compact construction make it suitable for compatible residential and commercial final circuits requiring high short-circuit performance.

Enhanced Arc Fault and High-Capacity Overcurrent Protection
Arc fault detection devices monitor electrical circuits for characteristics associated with potentially dangerous electrical arcing. The ABB S-ARC1 M is designed to protect end-user single-phase circuits against earth, parallel and series arc faults, while its integrated miniature circuit breaker provides thermal-magnetic protection against overloads and short-circuit currents.
The S-ARC1 M range provides enhanced short-circuit performance compared with the standard S-ARC1 range, with the S-ARC1 M B10 providing a 10 kA ultimate short-circuit breaking capacity. Combining AFDD and MCB functionality within a compact two-module device helps simplify distribution board design while providing protection against electrical faults that conventional MCBs alone are not designed to detect.
Typical Applications
- Residential electrical distribution boards.
- Commercial electrical distribution systems.
- Single-phase final circuits requiring enhanced arc fault protection.
