Why Choose the ABB S-ARC1 M C32 Arc Fault Detection Device?
The ABB S-ARC1 M C32 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 C32 monitors the electrical circuit for characteristics associated with hazardous arc faults and disconnects the affected circuit when necessary. Its integrated MCB provides protection against overloads and short circuits, allowing arc fault detection and overcurrent protection to be incorporated within a single DIN rail device.
With a rated current of 32 A, a C tripping characteristic and a 10 kA rated short-circuit breaking capacity, the S-ARC1 M C32 is suitable for circuits where moderate starting or inrush currents may occur. Its compact 1P+N configuration occupies only two modules within the distribution board, helping simplify installation while conserving valuable panel space.

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 C32 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 32 A C-curve circuit protection.
