      What this product is for

      This front-mount auxiliary contact block adds 2NO+2NC auxiliary contacts to compatible Noark Ex9C and Ex9CR contactors rated from 9A to 500A. It is used where additional control, status indication, electrical interlocking, or PLC input points are required in motor control and automation assemblies.

      Use for

      • Adding extra auxiliary contacts to Noark Ex9C and Ex9CR contactors
      • Motor starter panels, control panels, and OEM assemblies
      • Run status, seal-in, permissive, and interlock circuits
      • Forward/reverse contactor assemblies where extra signalling contacts are needed

      Avoid for

      • Use with non-compatible contactor series
      • Applications needing side-mount accessories instead of front-mount accessories
      • Installations requiring a different contact arrangement such as 1NO+1NC or 3NO+1NC

      Best for

      Best for panel builders, maintenance electricians, and OEMs standardizing on Noark Ex9C or Ex9CR contactors and needing a field-installable front accessory with 2NO+2NC contact arrangement.

      Installed in

      Typically installed in industrial control panels, machinery panels, HVAC control assemblies, pump controls, and commercial motor control systems. Its compact front-mount format helps add control points without changing the main contactor selection.

      Why this product exists

      Some contactor applications need more auxiliary contacts than the base device provides. This accessory expands available control contacts for indication, interlocking, and logic functions while matching the Ex9C/Ex9CR platform.

      Typical guidance: auxiliary contacts like this are commonly used for pilot lights, PLC status feedback, and electrical interlocks in reversing or sequential control schemes. Actual circuit design depends on the control voltage, load type, and local electrical code.

      Compared with similar products

      Compared with side-mount auxiliary blocks, this model mounts on the front of compatible Ex9C and Ex9CR contactors. Compared with other AX42-series options, AX4222UL provides a balanced 2NO+2NC arrangement, which is often preferred when both make and break auxiliary functions are needed in the same control scheme.
