General Electric THAUX21D Auxiliary Contact Block adds auxiliary contacts to a GE control relay or contactor, enabling additional signaling and interlock functionality in control panels. This module is mounted onto compatible GE devices to extend their control circuit capabilities, letting you monitor status or drive auxiliary circuits without replacing the main relay. The THAUX21D is a purpose-built add-on that integrates with GE automation hardware to simplify control scheme expansion in industrial electrical systems.
