ABB S-ARC1 M C40 (2CSA275901R9404) arc fault detection device with integrated MCB: 1P+N, C curve, 40 A, 10 kA breaking capacity.
£177.47
The ABB S-ARC1 M C40 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 C40 monitors the electrical circuit for characteristics associated with hazardous arc faults and disconnects the affected circuit when necessary. Its integrated MCB provides overload and short-circuit protection, allowing arc fault detection and overcurrent protection to be incorporated within a single DIN rail device while helping simplify distribution-board design.
With a rated current of 40 A, a C tripping characteristic and a 10 kA short-circuit breaking capacity, the S-ARC1 M C40 is suitable for higher-current circuits and loads where moderate starting or inrush currents may occur. Its compact 1P+N configuration occupies only two modules, providing comprehensive circuit protection without unnecessarily increasing distribution-board space requirements.
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 C40 therefore provides arc fault, overload and short-circuit protection within a compact two-module enclosure, helping simplify modern electrical distribution-board design while providing enhanced protection against electrically induced fires.
