Allen-Bradley 837-A7EX15A Temperature Switch

Allen-Bradley 837-A7EX15A Temperature Switch is a remote-bulb, capillary-driven temperature control unit from Rockwell Automation's 837 Bulletin family. The sensing bulb is placed at the critical spot in a piece of equipment, with the capillary leading to a snap-action switch mounted in a nearby enclosure, enabling precise, reliable temperature control in industrial environments. It actuates at a set range of 200 to 360°F, providing dependable switching to protect equipment from overheating in process applications, and the remote sensing arrangement allows the main switch to be located away from the hot zone for safer wiring and easier access. The 837 series supports installation in a variety of enclosures, including NEMA Type 1, 4, and 4X configurations, and is designed for remote sensing and rugged enclosure protection. This exact variant is listed in catalogs as discontinued, which can affect availability and replacement options.
