Why Choose the ABB S-ARC1 M C25 Arc Fault Detection Device?
The ABB S-ARC1 M C25 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 advanced arc fault detection with conventional overcurrent protection in a space-saving two-module device for residential, commercial and other building electrical installations.
The S-ARC1 M C25 monitors the electrical circuit for characteristics associated with hazardous series, parallel and earth arc faults and disconnects the affected circuit when necessary. Its integrated MCB provides overload and short-circuit protection, while continuous internal self-testing and LED indication support reliable operation and make troubleshooting easier following a trip.
With a rated current of 25 A, a C tripping characteristic and a 10 kA breaking capacity, the S-ARC1 M C25 is suitable for circuits where moderate starting or inrush currents may occur. It operates at 230–240 V AC and its compact 1P+N configuration occupies only two modules within a standard DIN rail 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 C25 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.
Typical Applications
- Residential electrical distribution boards.
- Commercial buildings and offices.
- Electrical circuits requiring enhanced protection against arc faults.
- Circuits supplying equipment with moderate starting or inrush currents.
- Fixed-equipment and suitable final circuits.
- Low-voltage distribution systems requiring 25 A C-curve circuit protection.
