ABB AUX. CONTACT NO+NC BELOW 125A,NF OA2G11

Why Choose the ABB OA2G11 Auxiliary Contact?

The ABB OA2G11 is a compact and reliable auxiliary contact block designed for use with compatible ABB low voltage switching equipment, including selected OT switch-disconnector and switch fuse ranges. It provides dependable electrical signalling for monitoring switch position and integrating switching devices into control, indication and automation circuits.

Featuring 1 normally open (1NO) and 1 normally closed (1NC) auxiliary contact, the OA2G11 allows clear status feedback from compatible ABB disconnect switches. This makes it ideal for control panels where remote indication, electrical interlocking, PLC input signalling or machine control feedback is required.

With a compact accessory design, 16 A conventional thermal current rating and practical screw terminal connections, the ABB OA2G11 is a robust and space-saving solution for industrial electrical installations, panel building and automation applications.

Reliable Auxiliary Switching for Control Panels

Auxiliary contacts such as the ABB OA2G11 are used to provide electrical feedback from a main switching device. This allows engineers to monitor whether a switch is open or closed and send that information to pilot lights, relays, PLC inputs or broader automation systems.

The OA2G11 is especially useful where both normally open and normally closed signalling is required from the same accessory. Its compact design helps save space inside control cabinets while maintaining dependable switching performance for industrial installations.

Typical Applications

• Industrial control panels and switchgear assemblies.
• Remote switch position indication.
• PLC and automation system feedback.
• Electrical interlocking circuits.
• Machine control and monitoring systems.
• Compatible ABB OT switch-disconnector installations.

Trusted by Panel Builders and Industrial Engineers

ABB auxiliary contacts such as the OA2G11 are widely used in industrial switchgear and control panel applications where reliable signalling, compact installation and dependable electrical performance are required.
