      • Installation requires a verified match to the documented ABB product family, the connected assemblies and the approved configuration.

      REA107-AA is an ABB arc-protection extension unit selected by its complete product identity and documented equipment role. Its suitability depends on the installed the documented ABB product family system, hardware execution, interfaces and application requirements matching the supplied unit. Visual similarity or a shortened code is not proof of interchangeability.

      Before replacing REA107-AA, record the full nameplate, installed position, connector or terminal arrangement, paired equipment and relevant ABB service information. After installation, verify power, communication and control interfaces, complete the approved functional checks and confirm stable operation before returning the equipment to service.

      This arc-protection extension unit extends the documented arc-flash light-sensing and trip system. Match the complete ABB identity and receiving-equipment record before installation.

      Keep REA107-AA on the documented signal, bus or power path. Preserve connector orientation, installed position and approved settings.

      After replacement, compare diagnostics with the saved baseline and prove the assigned arc-protection extension unit function under controlled test conditions.

      Technical notes

      REA107-AA is controlled by its complete ABB identity and installed-system record. Confirm REA107-AA, REA107-AA, the receiving equipment, connectors, hardware revision and approved configuration before replacement. Apply the documented isolation and ESD controls, then verify power, diagnostics, communication or I/O status and the assigned function before process release.
