Description
The York 325-40393-000 High Pressure Cutout Switch is used for pressure levels and breaking the operation when it is too high in chiller and air conditioning HVAC systems and it is a high-pressure safety switch that prevents damage to the compressor. It works by detecting pressure in the system, and breaking the electrical circuit when it exceeds a preset limit to protect the compressor. It is connected to pressure lines and electrical connections and has a secured refrigerant circuit, and is wired into the control system. Its operation aids in the safety of the system under overpressure conditions.
