Overview
The ABB REA101 is part of the REA arc protection system, engineered to detect and respond to arc faults in air-insulated switchgear panels. It uses optical sensors to detect the intense light emitted during an arc flash and can optionally combine this with overcurrent detection for enhanced selectivity.
This relay is designed to issue trip commands within milliseconds, significantly reducing the risk of injury and equipment damage. It supports modular configuration, allowing users to tailor the system to specific switchgear layouts. Moreover, it is compatible with IEC 61850-based automation systems, making it suitable for both new installations and retrofit projects.
The REA101 is widely used in power distribution, industrial plants, and renewable energy systems, where fast fault isolation is critical to maintaining operational safety and continuity.
Technical Data
| Parameter | Specification |

| Product Model | REA101 |
| Function | Arc fault detection and protection |
| Operating Temperature Range | –25°C to +70°C |
Typical Applications
The REA101 is deployed in low- and medium-voltage switchgear to detect arc faults and initiate fast tripping of circuit breakers.
Examples include:
-
Metal-clad switchgear panels, isolating a faulted compartment before pressure buildup or thermal damage occurs.
-
Industrial substations, data centers, and critical infrastructure where personnel safety and asset protection are paramount.
Its modular design and flexible sensor options make it ideal for custom switchgear configurations and multi-compartment panels.
Additionally, its fast response and integration capabilities support digital substations, smart grid deployments, and IEC 61850-based automation systems.
