Product Details

Description

This premium thermal limit switch is a critical safety component designed for HVAC systems and heating equipment. As a high-limit control fan disc, it functions by monitoring the internal temperature of your appliance and automatically interrupting the electrical circuit if temperatures reach the 150°F threshold. This prevents overheating, protecting internal components from heat damage and ensuring safe operation. Ideal for use in furnaces and air handlers, this thermal cutout is a common replacement part for systems experiencing frequent cycling or safety shut-offs. Its reliable 150F opening point makes it an essential hardware piece for maintaining climate control systems and ensuring long-term equipment durability.
