S-ARC1 M B6 Arc Fault Detection Device (AFDD) with MCB – 1P+N – B – 6 A – 10 kA

Why Choose the ABB S-ARC1 M B6 Arc Fault Detection Device?

The ABB S-ARC1 M B6 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 B6 continuously monitors the electrical circuit for characteristics associated with hazardous series, parallel and earth arc faults and disconnects the affected circuit when necessary. Its integrated thermal-magnetic MCB also provides overload and short-circuit protection, while a continuous internal self-test and LED indication support reliable operation and easier troubleshooting.

With a rated current of 6 A, a B tripping characteristic and a 10 kA rated short-circuit breaking capacity, the S-ARC1 M B6 is well suited to lower-current final circuits requiring enhanced protection. 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 B6 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.
• Lighting circuits requiring 6 A B-curve protection.
• Control and auxiliary electrical circuits.
• Final circuits requiring enhanced protection against electrical arc faults.
• Buildings containing valuable or difficult-to-replace assets.
