Description
About the OA1G10AU
About the OA1G10AU
The ABB 1SCA022436R7910 OA1G10AU is a single normally-open auxiliary contact block for enclosed change-over and transfer switches, rated 16 A conventional thermal current and 690 V insulation voltage. It signals switch position to a control or monitoring circuit, separate from the main power contacts. The block measures 11 x 37 x 21 mm and weighs 0.015 kg.
Selection Notes
With a single NO contact, this block reports one switch state (for example open or closed) to an external circuit; use the NC auxiliary contact variant in the same accessory range instead when the monitoring logic needs a normally-closed signal. The 690 V rated and insulation voltage matches the enclosed change-over and transfer switch range this contact block is built for, so it needs no separate derating when fitted to those switches.
