Rheem-Ruud 47-22712-82 Limit Switch Manual Reset 310°F

The Rheem-Ruud 47-22712-82 Limit Switch is an accessory that is used in HVAC systems to prevent the systems from overheating. This switch is designed for 230 VAC and 25A and thus it can work under the most challenging conditions. It has the SPST normally closed contact that opens at 310 F and self-closes at - 31 F. The manual reset function increases safety by requiring the reset after an over-temperature event, thus avoiding auto-start until the system is reviewed. This limit switch is utilized in Rheem and Ruud heating and cooling equipment including furnaces and air handlers. One of its major functions is to regulate the temperature inside the unit and disconnect the electrical circuit if the temperature rises beyond the permissible level.
