How to use
The ABB OA2G11 is designed for quick and secure mounting directly onto the compatible switch-disconnector. Before installation, ensure that the main power supply to the switchgear is disconnected to prevent accidental contact. Align the contact block with the designated mounting interface on the switch-disconnector and snap it into place according to the manufacturer's installation instructions. Once mounted, connect the control wires to the appropriate terminals, ensuring that all connections are tightened to the specified torque to prevent loose contacts.
What to consider before purchase
Verify that your switch-disconnector model belongs to the OT16-125F series.
Ensure the control circuit voltage and current requirements match the contact block ratings.
Confirm that there is sufficient physical space within the enclosure for the additional block.
Usage recommendations: Always perform a functional test after installation to verify that the auxiliary contacts correctly reflect the position of the main switch before putting the system into full operation.
