Why Choose the ABB S-ARC1 M B32 Arc Fault Detection Device?
The ABB S-ARC1 M B32 is a compact and highly capable 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 and overcurrent protection in a space-saving two-module device for residential, commercial and other building electrical installations.
The S-ARC1 M B32 monitors the electrical circuit for characteristics associated with hazardous series, parallel and earth arc faults and disconnects the affected circuit when a dangerous arc condition is detected. Its integrated thermal-magnetic MCB also provides conventional overload and short-circuit protection, allowing multiple protective functions to be incorporated within a single DIN rail device.
With a rated current of 32 A, a B tripping characteristic and a 10 kA rated short-circuit breaking capacity, the S-ARC1 M B32 is suitable for demanding low-voltage final circuits. It operates at a rated voltage of 230–240 V AC and its compact 1P+N configuration occupies 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 cause sufficient current to operate conventional overcurrent protection, an AFDD monitors the circuit for characteristic electrical signatures associated with hazardous arcs and disconnects the affected circuit when necessary.
The ABB S-ARC1 M series combines this arc fault detection technology with an integrated miniature circuit breaker. The S-ARC1 M B32 therefore provides protection against arc faults, overloads and short circuits within a compact two-module enclosure, helping simplify modern electrical distribution-board design while providing enhanced protection against electrically induced fires.
Typical Applications
- Residential electrical distribution boards.
- Commercial buildings and offices.
- Electrical circuits requiring enhanced protection against arc faults.
- Socket and fixed-equipment final circuits.
- Buildings containing valuable or difficult-to-replace assets.
- Low-voltage distribution systems requiring 32 A B-curve circuit protection.
