Eaton NSB-C320KGTY4 Auxiliary Contact is a four-contact signaling block featuring two normally open (NO) contacts and two normally closed (NC) contacts. Manufactured by Eaton, this auxiliary contact provides discrete feedback and interlock capabilities for control circuits without carrying the main power load. The 2NO/2NC configuration supports monitoring and control logic in compact panel installations and can be used to signal states or enable interlocks in electrical assemblies that require both active-high and active-low signaling paths.
