Description
The York S1-3500-3151/A Auto Limit Switch L155-55F is a component used to maintain and regulate temperature by disconnecting the circuit when a predetermined high temperature is reached and by automatically reconnecting to the circuit when the temperature drops to a lower level in HVAC systems. It works on a component that reacts to the change in heat and prevents overheating. This limit switch is designed to protect heat sources, such as heat exchangers or combustion areas, and is attached to the control circuit, as well as the temperature and air handlers, and other heating areas of the equipment.
