DS-ARC1 M B16 A30 Arc Fault Detection Device (AFDD) with RCBO – 1P+N – B – 16 A – 30 mA Type A – 10 kA

Why Choose the ABB DS-ARC1 M B16 A30 Arc Fault Detection Device?

The ABB DS-ARC1 M B16 A30 is a compact 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 M series, it combines arc fault detection, residual current protection, overload protection and short-circuit protection within a single three-module DIN rail device.

The DS-ARC1 M is designed to detect series, parallel and earth arc faults while its integrated Type A RCBO provides protection against residual currents, overloads and short circuits. The device also incorporates AFDD-related overvoltage protection, helping consolidate multiple electrical protection functions within one compact unit.

With a rated current of 16 A, a B tripping characteristic, 30 mA Type A residual current sensitivity and a rated operational voltage of 230–240 V AC, the DS-ARC1 M B16 A30 provides enhanced protection for 1P+N circuits. The M version offers a 10 kA rated ultimate short-circuit breaking capacity, making it suitable for installations requiring a higher breaking capacity than the standard DS-ARC1 range.
