SUPCO Temperature Limit Controller

Surface mount limit controls provide fail-safe controls for temperatures above the safety limit. They operate using temperature-sensitive metals that change shape and disconnect the connected circuit when the trigger temperature is reached. They are installed on flat surfaces using two mounting holes and fasteners to hold them in place. Depending on their configuration, their trigger temperature can be fixed or adjusted, and their reset can be manual or automatic. They are commonly used as protection devices to turn systems on or off when temperatures exceed or drop below their setpoint.
