Overview

The ABB OA3G01 is a 1NC (Normally Closed) auxiliary contact block designed for use with ABB OT200 to OT2000 series disconnect switches. This component provides essential circuit monitoring and signaling capabilities within industrial switchgear and automation systems. With a current rating of 16A and an IP20 rating, it ensures reliable operation in standard industrial environments. The OA3G01 features early-make functionality, meaning its contacts break before the main contacts of the disconnect switch open, which is critical for interlocking and status indication. It adheres to EN 50013 contact numbering standards. The compact design allows for the installation of up to 8 auxiliary contact units per OEA28 module on the specified disconnect switches. This auxiliary contact is manufactured by ABB - Electrification (SKU: OA3G01) and is made in Germany (DE). It is suitable for applications requiring reliable status feedback and interlocking in motor control centers and other automation setups.
