DS-ARC1 B10 A30 Arc Fault Detection Device (AFDD) with RCBO – 1P+N – B – 10 A – 30 mA Type A – 6 kA

Why Choose the ABB DS-ARC1 B10 A30 Arc Fault Detection Device?

The ABB DS-ARC1 B10 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 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 helps detect dangerous electrical arc faults that conventional circuit protection devices may not identify, while also providing Type A residual current protection and thermal-magnetic overcurrent protection. Continuous internal self-testing monitors the arc fault detection functionality, while front-mounted indication assists with troubleshooting and operating status identification.

With a rated current of 10 A, B tripping characteristic, 30 mA residual current sensitivity and a rated operational voltage of 230–240 V AC, the DS-ARC1 B10 A30 provides a space-efficient protection solution for electrical installations where enhanced protection against arc faults, earth leakage, overloads and short circuits is required.

Comprehensive Electrical Circuit Protection

Arc fault detection devices monitor electrical circuits for characteristic conditions associated with potentially dangerous electrical arcs. The ABB DS-ARC1 combines this functionality with residual current and overcurrent protection, enabling a single device to provide protection against arc faults, earth leakage currents, overloads and short circuits.

The DS-ARC1 series incorporates continuous internal self-testing of the arc fault detection function and provides front-panel indication to assist fault identification. Its three-module format and DIN rail mounting make it suitable for integration into modern distribution boards while maintaining a compact installation footprint.
