Product Overview
Designed as a direct OEM replacement for Rheem and Ruud heating systems, the 47-25350-02 limit switch monitors supply air or heat exchanger temperatures to prevent equipment damage and unsafe operating conditions. When temperatures exceed the 210°F fixed open setpoint, the normally closed switch opens to interrupt the heating circuit. Once temperatures drop back to the 190°F fixed close setpoint, the switch automatically resets — restoring normal operation without manual intervention.
