OA2G11 is an auxiliary contact block designed for use with low-voltage enclosed switches, switch-disconnectors, and safety switches. It features one normally closed (NC) contact and one normally open (NO) contact, with a conventional thermal current rating of 16 A. The contact block has compact dimensions of 60 mm length, 50 mm height, and 10 mm depth, with a net weight of 0.020 kg, making it suitable for integration into enclosed switch assemblies. The OA2G11 is compatible with switch-disconnectors in the OT 16...125F range and is designed to provide reliable auxiliary switching functionality in industrial control and safety applications.
