Features:
- Arc Protection Extension Unit function for the documented ABB REA arc protection system platform.
- REA107-AA RLY-REA107-AAA is intended for 250 V dc/ac installations whose complete hardware and installed configuration match the original equipment.
- REA107-AA RLY-REA107-AAA uses the documented -40... +100 °C specification and requires confirmation against the supplied item and installed ABB configuration.
REA107-AA RLY-REA107-AAA is a ABB arc protection extension unit for the ABB REA arc protection system. The documented identity places it in the ABB REA product family and defines its role as arc protection extension unit within the installed control or monitoring architecture. The REA107-AA RLY-REA107-AAA must be selected by its complete ABB article number, documented hardware execution, installed position and every mechanical or electrical interface that determines compatibility. Visual similarity alone does not establish interchangeability, so the supplied unit must be compared with the original equipment and approved service record before installation.
The available manufacturer-family information records maximum system voltage: 250 V dc/ac; normal service temperature range: -40... +100 °C; operating time from the light: < 1.0 ms. Before replacement, compare the complete nameplate, receiving hardware, connector or terminal arrangement and approved project documentation; after installation, verify diagnostics and every affected signal or communication path before process release.
The REA107-AA RLY-REA107-AAA ABB Arc Protection Extension Unit is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB REA107-AA RLY-REA107-AAA documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
REA107-AA RLY-REA107-AAA is a ABB arc protection extension unit for the ABB REA arc protection system. The documented identity places it in the ABB REA product family and defines its role as arc protection extension unit within the installed control or monitoring architecture.
The listed parameters are limited to the documented model or product-family evidence. Do not import ratings from a similar part number; compare the exact label, slot or carrier, terminal map and connected equipment.
REA107-AA RLY-REA107-AAA must remain matched to the documented ABB REA arc protection system installation. Confirm the receiving hardware generation, connector or terminal arrangement, software or configuration dependencies and system drawings before approving the item.
Photograph labels and connections before removal and preserve the original position, keying, addressing and channel allocation.
Isolate the equipment using the approved procedure, verify all stored energy is removed and inspect the receiving hardware before fitting REA107-AA RLY-REA107-AAA.
After installation, restore power in the documented sequence, review diagnostics and test every affected signal, relay, network, control or protection function against the commissioning record.
