Eaton XTPAXSA21 Auxiliary Contact

Product Description

The EATON XTPAXSA21 is an auxiliary contact designed for use with compatible Eaton contactors and motor starters. Auxiliary contacts expand the switching capability of the main device by providing additional signal or control circuit contacts that operate in conjunction with the primary contactor coil. Electricians and industrial maintenance technicians install these contacts to enable status indication, interlocking, or control-circuit feedback in motor control and load management applications. The XTPAXSA21 is a compact, add-on unit that mounts directly to the host device without requiring separate mounting hardware.

This auxiliary contact is suited for commercial and industrial electrical installations where motor control centers, control panels, or starter assemblies require supplemental contact points. Typical applications include conveyor systems, pump controls, HVAC fan and compressor starters, and general-purpose motor control panels. It is installed by licensed electricians or qualified industrial maintenance personnel working within standard motor control enclosures.
