Allen-Bradley 508TX-A Motor Starter Contactor Assembly

The Allen-Bradley 508TX-A is a magnetic motor starter and contactor assembly designed for across-the-line starting of three-phase AC motors in industrial applications. Part of Allen-Bradley's legacy NEMA Motor Control line, the 508TX-A combines an electromagnetic contactor with overload protection to provide reliable motor starting and stopping. This non-reversing, panel-mount starter uses an open-style enclosure and is designed for full-voltage control at 50/60 Hz, suitable for three-phase squirrel-cage motors in pumps, conveyors, compressors, fans, and other industrial machinery. It supports integration with pilot devices such as push buttons, pressure switches, float switches, thermostats, and other controls to automate operation and safeguard connected equipment from overload. As a legacy replacement component from Allen-Bradley/Rockwell Automation, it remains a common choice in industrial indoor environments where robust NEMA motor control equipment is required.
