DS-ARC1 C20 A30 Arc Fault Detection Device (AFDD) with RCBO – 1P+N – C – 20 A – 30 mA Type A – 6 kA

Why Choose the ABB DS-ARC1 C20 A30 Arc Fault Detection Device?

The ABB DS-ARC1 C20 A30 is a compact and highly reliable arc fault detection device (AFDD) with integrated RCBO protection designed to provide comprehensive protection for single-phase electrical circuits. As part of the advanced ABB DS-ARC1 series, it combines arc fault detection, residual current protection, overload protection and short-circuit protection within a single three-module DIN rail device.

This integrated protection solution is designed to protect against series, parallel and earth arc faults while also providing Type A residual current protection and thermal-magnetic overcurrent protection. The DS-ARC1 also provides overvoltage protection, bringing multiple protective functions together in one compact device for enhanced electrical safety and simplified distribution board design.

With a rated current of 20 A, a C tripping characteristic, 30 mA Type A residual current sensitivity and a 230–240 V AC rated operational voltage, the DS-ARC1 C20 A30 is suitable for single-phase circuits requiring enhanced protection. Its C-curve characteristic makes it suitable for circuits with moderate inrush currents, while its compact DIN rail format enables straightforward integration into electrical distribution boards.
