Description
The Supco SHM160 is a snap disc manual reset limit switch engineered for reliable over-temperature protection in HVAC and heating equipment. With a fixed 160°F cut-out temperature and open-on-rise switch action, this device interrupts the circuit when the monitored surface or air stream reaches the set point, preventing equipment damage and potential safety hazards. Manual reset operation ensures that a technician must physically inspect and reset the device before the system can resume operation — a critical safety feature in high-stakes heating applications.
The SHM160 ships complete with an adapter flange plate, simplifying installation on a wide range of furnaces, air handlers, duct systems, and other HVAC equipment where secure, flush mounting is required.
