Description
The York S1-02531988000 Thermal Expansion Valve Bolt-On is electromagnetic power-switching equipment used to control the connection and interruption of high-voltage electrical power to compressors and blower motors. It provides stable electrical switching for stable equipment in HVAC systems. It is placed inside the control panels of commercial heating and cooling units, where low-voltage commands energize the coil to close the main contacts and supply power to connected components. It works as the load-switching component, supporting proper equipment operation, coordinated electrical control, and consistent power distribution during normal operating cycles.
