Why Choose the ABB DS-ARC1 B20 A30 Arc Fault Detection Device?
The ABB DS-ARC1 B20 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 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 detects potentially dangerous series and parallel electrical arc faults while also providing Type A residual current protection and thermal-magnetic overcurrent protection. The DS-ARC1 also incorporates internal testing and fault indication functions, helping provide enhanced protection and easier identification of electrical faults.
With a rated current of 20 A, a B tripping characteristic and 30 mA Type A residual current sensitivity, the DS-ARC1 B20 A30 is designed for 230–240 V AC 1P+N circuits. Its compact DIN rail format makes it suitable for residential, commercial and light industrial electrical installations requiring enhanced protection against arc faults, earth leakage, overloads and short circuits.
