Features:
- Arc Protection Relay function for the documented ABB REA arc protection system platform.
- REA101-AA RLY-REA101-AAAG uses the documented 250 V DC/AC specification and requires confirmation against the supplied item and installed ABB configuration.
- REA101-AA RLY-REA101-AAAG uses the documented 5 A specification and requires confirmation against the supplied item and installed ABB configuration.
REA101-AA RLY-REA101-AAAG is a ABB arc protection relay 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 relay within the installed control or monitoring architecture. The REA101-AA RLY-REA101-AAAG 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 rated voltage: 250 V DC/AC; continuous carry: 5 A; minimum pulse length: 1 s. 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 REA101-AA RLY-REA101-AAAG ABB Arc Protection Relay is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB REA101-AA RLY-REA101-AAAG 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.
REA101-AA RLY-REA101-AAAG is a ABB arc protection relay 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 relay 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.
REA101-AA RLY-REA101-AAAG 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 REA101-AA RLY-REA101-AAAG.
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.
