The Enviro-Tec PE-09-8140 is a one-time limit switch designed to provide non-resettable thermal protection in HVAC fan coil and air handling systems. Rated for a 140°F cut-out temperature, this safety device permanently opens the circuit when the specified temperature is exceeded, preventing continued operation under unsafe conditions. Commonly used as a fail-safe in heating sections or critical components, it helps protect equipment from overheating and potential damage. This limit switch is intended for replacement in Enviro-Tec units and similar applications requiring a single-use thermal safety device.
