The Rheem-Ruud 47-22712-82 Limit Switch, device designed to protect HVAC systems from overheating. Rated at 230 VAC and 25A, this switch ensures reliable operation under demanding conditions. It features a SPST configuration with normally closed contacts, which open at 310°F and automatically close at -31°F. The manual reset function provides added safety by requiring a reset after an over-temperature event, preventing automatic restart until the system is inspected.

Its primary role is to monitor the temperature within the unit, cutting off the electrical circuit if temperatures exceed safe operating limits.
