This ProTech limit switch is a safety device designed for use in a variety of Rheem furnaces. It functions as an automatic reset temperature control, monitoring system temperatures to prevent overheating by opening the electrical circuit when the temperature rises to 170°F and closing it again once it cools to 150°F.Engineered as a single-pole, single-throw (SPST) normally closed switch, this component is designed for board mounting. Its reliable operation and precise temperature sensing make it an essential replacement part for maintaining the safety and performance of compatible HVAC systems.

  • Temperature Operation:Features a normally closed SPST switch that opens at 170°F and closes at 150°F to protect equipment from over-temperature conditions.
  • Automatic Reset:Automatically resets when temperatures fall to a safe level, restoring system operation without requiring manual service.
  • Designed for Fit:Engineered for board mounting with a 90-degree strap angle, ensuring proper placement and secure installation in compatible units.
  • Quick Connection:Equipped with 3/16-inch quick-connect terminals to simplify the wiring process during replacement or service.
  • Durable Construction:Built with an enclosed disc face that protects the sensing element from damage and contaminants for reliable performance.
