## Long description

The auxiliary contact block Noark 108143 1NO+1NC AX51 11 is an add-on component designed for use with AX51 series contactors and motor starters. It provides one normally open (NO) and one normally closed (NC) contact to extend signaling and control capabilities in industrial electrical panels. The unit mounts directly onto compatible contactors to give reliable feedback and auxiliary switching functions without modifying the primary device.
Advantages
This auxiliary contact block delivers compact, space-saving auxiliary contacts engineered for straightforward mechanical mounting on matching contactors. The 1NO+1NC configuration enables flexible control logic and status indication while maintaining clear separation between switching circuits. The block is built to consistent electrical contact performance and provides a plain interface for interlocking, signaling, and automation tasks.
Suitable for
 Adding feedback contacts to motor starters and contactors
