S-ARC1 B10 Arc Fault Detection Device (AFDD) with MCB – 1P+N – B – 10 A – 6 kA

Why Choose the ABB S-ARC1 B10 Arc Fault Detection Device?

The ABB S-ARC1 B10 is a compact arc fault detection device (AFDD) with integrated miniature circuit breaker (MCB) designed to protect single-phase final circuits against electrical arc faults and overcurrents. As part of the ABB S-ARC1 series, it combines AFDD and thermal-magnetic circuit protection within a single two-module DIN rail device.

The S-ARC1 provides protection against series, parallel and earth arc faults as well as short circuits and overloads. By combining these protective functions in one device, it helps reduce the space required within distribution boards while providing enhanced protection against electrical faults that conventional miniature circuit breakers alone are not designed to detect.

With a rated current of 10 A, a B tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 B10 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 residential and commercial final-circuit protection.

Enhanced Arc Fault and Overcurrent Protection

Arc fault detection devices monitor electrical circuits for characteristic current patterns associated with potentially dangerous electrical arcing. The ABB S-ARC1 is designed to detect series, parallel and earth arc faults while its integrated miniature circuit breaker provides conventional thermal-magnetic protection against overloads and short circuits.

Combining AFDD and MCB functionality in a two-module device helps simplify distribution board design and provides enhanced protection for final circuits without requiring separate arc fault and overcurrent protection devices. The S-ARC1 range is designed for residential and commercial applications and complies with relevant AFDD and miniature circuit breaker standards.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical distribution systems.
• Single-phase final circuits requiring arc fault protection.
• Circuits protected at 10 A requiring a B tripping characteristic.
• Lighting and compatible low-current electrical circuits.
• Installations requiring combined arc fault, overload and short-circuit protection.
