Why Choose the ABB S-ARC1 M C6 Arc Fault Detection Device?
The ABB S-ARC1 M C6 is a compact and reliable arc fault detection device (AFDD) with integrated miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against dangerous arc faults, overloads and short circuits. As part of the ABB S-ARC1 M series, it combines arc fault detection with conventional overcurrent protection in a space-saving two-module device for residential and commercial electrical installations.
The S-ARC1 M C6 provides protection against series arc faults, parallel arc faults and earth arc faults, helping address electrical fault conditions that conventional overcurrent protection alone may not detect. Its integrated thermal-magnetic MCB also provides overload and short-circuit protection, combining multiple protective functions within a single DIN rail device.
With a rated current of 6 A, a C tripping characteristic and a 10 kA rated short-circuit breaking capacity, the S-ARC1 M C6 is well suited to lower-current circuits where moderate starting or inrush currents may occur. It operates at 230–240 V AC and uses a compact 1P+N configuration occupying only two modules within the distribution board.

Reliable Arc Fault and Circuit Protection
Arc faults can develop as a result of damaged conductors, deteriorated insulation, loose electrical connections and other installation faults. Because some dangerous arcing conditions may not draw sufficient current to operate conventional overcurrent protection, an AFDD monitors the circuit for electrical characteristics associated with hazardous arcs and disconnects the affected circuit when required.
The ABB S-ARC1 M series combines arc fault detection technology with an integrated miniature circuit breaker. The S-ARC1 M C6 therefore provides protection against series, parallel and earth arc faults as well as overloads and short circuits within a compact two-module enclosure, helping simplify modern electrical distribution-board design while providing enhanced circuit protection.
Typical Applications

- Commercial buildings and offices.
- Lighting circuits.
- Control and auxiliary circuits.
- Circuits with equipment producing moderate starting or inrush currents.
- Final circuits requiring enhanced protection against electrical arc faults.
- Low-voltage distribution systems requiring 6 A C-curve circuit protection.
