Caloritech ARO464 Thermostat

Caloritech ARO464 (also listed as AR0464) is a line‑voltage, DPST thermostat designed for Caloritech AR Series immersion heaters. It employs an open‑on‑rise configuration and is rated for 277 VAC and up to 25 A, making it suitable for high‑current heater circuits in commercial and industrial equipment. With a control range of -18 to 40°C (0°F to 100°F) and a non‑programmable mechanical setpoint, it provides straightforward temperature control to prevent overheating. The ARO464/AR0464 is intended for installation in AR‑series heater assemblies and is commonly used to regulate water or other compatible liquids in industrial heating applications. Variants appear under model identifiers such as AR0464 and ARO464EPA2 across retailers, but share core specs: DPST switching, -18°C to 40°C range, 277 VAC supply, open‑on‑rise operation, and Caloritech AR‑series compatibility.
