Why Choose the ABB S-ARC1 C10 Arc Fault Detection Device?
The ABB S-ARC1 C10 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 protect electrical circuits against potentially hazardous arc faults while its integrated MCB provides conventional protection against overloads and short circuits. Combining these functions in one device helps provide enhanced circuit protection without requiring separate AFDD and MCB modules.
With a rated current of 10 A, a C tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 C10 is designed for 1P+N single-phase circuits. It provides a 6 kA rated service short-circuit breaking capacity and a 7.5 kA rated ultimate short-circuit breaking capacity, making it suitable for compatible residential and commercial final circuits.

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 also makes the S-ARC1 C10 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 10 A requiring a C tripping characteristic.
- Lighting and compatible electrical circuits with moderate inrush currents.
- Installations where enhanced protection against electrically initiated fires is required.
- Installations requiring combined arc fault, overload and short-circuit protection.
