This is a very specific industrial part: a 135°F fixed-temperature thermostat designed for explosion-proof mounting. The 'EXPROOF' and 'UL' in the name mean it's built to be safe in hazardous locations where flammable gases, vapors, or dust might be present—think chemical plants, refineries, grain silos, or paint booths.
Part number is TH-302EPM135 from Thermotech. It's not a general home thermostat. It's a component that gets wired into equipment to automatically cut power or trigger an alarm if the temperature hits 135°F, helping prevent overheating in risky environments. If you need this part, you likely know exactly what it's for. Always verify the specs match your application's requirements before ordering.
