S-ARC1 C16 Arc Fault Detection Device (AFDD) with MCB – 1P+N – C – 16 A – 6 kA

Why Choose the ABB S-ARC1 C16 Arc Fault Detection Device?

The ABB S-ARC1 C16 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 is designed to detect potentially dangerous electrical arcing while its integrated MCB provides conventional protection against overloads and short circuits. This combined approach helps protect circuits against faults that a conventional MCB alone is not designed to detect, providing an additional level of protection against electrically initiated fires.

With a rated current of 16 A, a C tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 C16 is designed for 1P+N single-phase circuits. Its 6 kA short-circuit 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 identified, the ABB S-ARC1 can disconnect the affected circuit, while its integrated miniature circuit breaker provides thermal-magnetic protection against overloads and short-circuit currents.

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. The C tripping characteristic of the S-ARC1 C16 also makes it suitable for compatible circuits where moderate starting or inrush currents may occur.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical distribution systems.
• Single-phase final circuits requiring enhanced arc fault protection.
• Circuits protected at 16 A requiring a C tripping characteristic.
• Compatible lighting and general-purpose electrical circuits.
