The Eaton NSB C320KGS32 Auxiliary Contact Block is a side-mounted accessory that extends the signaling capabilities of Eaton NSB equipment. It provides one normally open (NO) and one normally closed (NC) contact, enabling separate control paths within a single auxiliary block. The part number C320KGS32 uniquely identifies this two-contact block in the NSB family. Designed to be installed alongside compatible NSB assemblies, this auxiliary block adds a second contact set without modifying the main circuit.
