WHD-EA 3Contacts Mechanical Adjustable Copper Thermostat

WHD-EA mechanical 3 contacts adjustable capillary thermostat is a temperature control device specifically designed for various heating systems. It operates based on a mechanical switch mechanism, using a temperature-sensitive element to detect temperature changes and control the circuit accordingly.
WHD-EA thermostat is commonly used in equipment such as HVAC piping, water boilers, and disinfection cabinet panels, as these devices require stable temperature control. Its mechanical design ensures reliable performance and does not require external power supply, making it suitable for environments where electronic solutions may not be practical.
