DS-ARC1 M C20 A30 Arc Fault Detection Device (AFDD) with RCBO – 1P+N – C – 20 A – 30 mA Type A – 10 kA

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

The ABB DS-ARC1 M C20 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 protect against earth, parallel and series arc faults while its integrated Type A RCBO provides protection against earth fault currents, overloads and short circuits. The device also provides overvoltage protection, bringing several important electrical protection functions together within one compact unit.

With a rated current of 20 A, a C tripping characteristic and 30 mA Type A residual current sensitivity, the DS-ARC1 M C20 A30 provides enhanced protection for 1P+N circuits. Its 7.5 kA rated service short-circuit breaking capacity and 10 kA rated ultimate short-circuit breaking capacity make it suitable for installations requiring robust circuit protection, while the C-curve characteristic accommodates circuits with moderate starting or inrush currents.

Comprehensive Electrical Circuit Protection

Arc fault detection devices monitor electrical circuits for conditions associated with potentially dangerous electrical arcs. The ABB DS-ARC1 M is designed to protect against earth, parallel and series arc faults and combines this functionality with Type A residual current and thermal-magnetic overcurrent protection, enabling a single device to address multiple electrical fault conditions.

The DS-ARC1 M range combines AFDD and RCBO functionality with a 10 kA rated ultimate short-circuit breaking capacity while retaining a compact three-module format. This integrated approach reduces the number of separate protective devices required and provides protection against arc faults, residual currents, overloads, short circuits and overvoltage conditions within one DIN rail unit.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical distribution systems.
• Single-phase final circuits requiring enhanced arc fault protection.
• Circuits protected at 20 A requiring a C tripping characteristic.
• Circuits with moderate equipment starting or inrush currents.
