S-ARC1 C6 Arc Fault Detection Device (AFDD) with MCB – 1P+N – C – 6 A – 6 kA

Why Choose the ABB S-ARC1 C6 Arc Fault Detection Device?

The ABB S-ARC1 C6 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 end-user circuits against earth, parallel and series arc faults as well as conventional overloads and short-circuit currents. By detecting potentially hazardous electrical arcing that conventional MCB protection alone is not designed to identify, the device provides an additional level of protection against electrical faults associated with damaged conductors, deteriorated insulation and poor connections.

With a rated current of 6 A, a C tripping characteristic and a rated frequency of 50–60 Hz, the S-ARC1 C6 is designed for 1P+N single-phase circuits. Its 6 kA short-circuit breaking capacity and C characteristic make it suitable for compatible low-current circuits where moderate starting or inrush currents may occur.

Enhanced Arc Fault and Overcurrent Protection

Arc fault detection devices monitor electrical circuits for characteristics associated with potentially dangerous electrical arcing. The ABB S-ARC1 is designed to protect end-user single-phase circuits against earth, parallel and series arc faults, 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 C6 also makes it suitable for compatible low-current 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 6 A requiring a C tripping characteristic.
• Compatible lighting and control circuits.
• Compatible low-current loads with moderate starting or inrush currents.
• Installations requiring combined arc fault, overload and short-circuit protection.
