Chromalox AR-5524 Temperature Control

Chromalox AR-5524 is a rugged DPST temperature control for electric heating elements, featuring bulb-and-capillary sensing and a 7-foot capillary lead. It provides precise temperature control in the 200\u00b0F\u2013550\u00b0F range and is designed for line voltages up to 277 VAC with a 30 A load rating in DPST configuration. This AR-series, non-indicating control uses a bulb and capillary to sense temperature and is commonly deployed in ovens, sterilizers, molding machines, heat-sealing equipment, and water baths, where robust mechanical control is preferred over electronic controllers. The controller is rated for an operating environment from \u221240\u00b0F to 150\u00b0F; it is intended to be used with an approved safety device, as AR controls are temperature controls that do not provide fail-safe protection by themselves. Capillary lengths and model variants exist, so confirm the exact length (7 ft in this variant) and electrical ratings for your installation.
