KT80

0°C to 120°C [32°F to 248°F] industrial capillary thermal overload tracking monitor and safety cut-out switch. Built with a fluid-filled copper remote sensing bulb connected via an armored capillary tube to activate an internal microswitch assembly upon over-temperature faults. Used to prevent catastrophic overheating failures inside commercial liquid boilers, industrial oil baths, and localized fluid storage vats. Industry-standard direct replacements and cross-manufacturers include Robertshaw KT-80, Ranco automatic cutouts, Johnson Controls equivalent switches, and Honeywell L4000 series limits.
