S-ARC1 B16 Arc Fault Detection Device (AFDD) with MCB – 1P+N – B – 16 A – 6 kA

Why Choose the ABB S-ARC1 B16 Arc Fault Detection Device?

The ABB S-ARC1 B16 is a compact arc fault detection device (AFDD) with integrated miniature circuit breaker (MCB) designed to provide enhanced protection for single-phase final circuits. As part of the ABB S-ARC1 series, it combines arc fault detection with thermal-magnetic overload and short-circuit protection within a single two-module DIN rail device.

The S-ARC1 detects potentially dangerous arc faults and disconnects the affected circuit, helping reduce the risk of electrical fires caused by damaged wiring, loose connections and other arcing conditions. Its integrated MCB provides conventional protection against overloads and short circuits, while an AFDD test button, continuous internal self-test and LED troubleshooting indication help simplify verification and fault diagnosis.

With a rated current of 16 A, a B tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 B16 is designed for 1P+N single-phase circuits. Its 6 kA breaking capacity and compact construction make it suitable for residential and commercial final circuits requiring combined arc fault, overload and short-circuit protection.

Enhanced Arc Fault and Overcurrent Protection

Arc fault detection devices monitor electrical circuits for characteristic conditions associated with potentially dangerous electrical arcing. When an arc fault is detected, the ABB S-ARC1 disconnects the affected circuit, helping reduce the risk of electrical fires while its integrated miniature circuit breaker provides thermal-magnetic protection against overloads and short circuits.

Combining AFDD and MCB functionality within a compact two-module device helps simplify distribution board design while providing protection against electrical faults that conventional MCBs alone are not designed to detect. Continuous internal self-testing, LED troubleshooting indication and a dedicated AFDD test button further support reliable operation and straightforward maintenance.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical distribution systems.
• Single-phase final circuits requiring arc fault protection.
• Circuits protected at 16 A requiring a B tripping characteristic.
• Socket, lighting and compatible general-purpose final circuits.
• Buildings containing valuable or difficult-to-replace equipment and materials.
• Installations requiring combined arc fault, overload and short-circuit protection.
