S-ARC1 C32 Arc Fault Detection Device (AFDD) with MCB – 1P+N – C – 32 A – 6 kA

Why Choose the ABB S-ARC1 C32 Arc Fault Detection Device?

The ABB S-ARC1 C32 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 single-phase circuits against earth arc faults, parallel arc faults and series arc faults, while its integrated MCB provides protection against overloads and short-circuit currents. This combination provides protection against electrical arcing conditions that conventional MCB protection alone is not designed to detect.

With a rated current of 32 A, a C tripping characteristic and a 6 kA short-circuit breaking capacity, the S-ARC1 C32 is suitable for compatible residential and commercial final circuits. Its C characteristic accommodates moderate starting and inrush currents, while its 1P+N configuration and compact construction support space-efficient installation in distribution boards.

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 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 C32 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 32 A requiring a C tripping characteristic.
• Compatible electrical loads with moderate starting or inrush currents.
• Installations where enhanced protection against electrically initiated fires is required.
• Installations requiring combined arc fault, overload and short-circuit protection.
