Product Details

Description

This premium L140-40F high limit switch is a critical safety component designed for HVAC systems and industrial heating equipment. Functioning as a thermal disc thermostat, it monitors system temperatures to prevent overheating by automatically breaking the electrical circuit when the temperature reaches 140°F. Known as an 'open on rise' control, it features a 40°F differential, resetting once the equipment has safely cooled. Ideal for furnace repair and routine HVAC maintenance, this durable fan disc switch ensures reliable operation and protects internal components from thermal damage. Its robust construction makes it a preferred choice for technicians looking for dependable high-limit protection in commercial and residential heating units.
