Description
The Supco SHM210 is a high-quality snap disc manual reset limit switch engineered for reliable over-temperature protection in HVAC heating systems, furnaces, and related equipment. Featuring a fixed 210°F cut-out temperature and an open-on-rise switch action, this limit switch interrupts the circuit when the sensed temperature exceeds the set point — safeguarding equipment and preventing hazardous conditions. The manual reset design ensures that the system cannot automatically restart after a trip event, requiring a deliberate reset by a technician and helping identify the root cause of overheating before returning to operation.
The included adapter flange plate simplifies installation and provides a secure, professional mounting solution on a variety of HVAC equipment surfaces.
