Description
The Liebert 303877P11S High Pressure Switch is used to regulate element pressure by opening, or closing contacts when the pressure reaches a predetermined level of 580 PSI. It uses an SPDT switching mechanism, which reacts to changes in pressure, allowing it to be controlled precisely and respond safely to pressure changes in HVAC systems, like precision cooling and data center air conditioning units, where pressure control is paramount. It is mounted in the refrigerant circuit, and communicates with control systems to turn off or turn on, depending on the pressure conditions. Its use assists in system protection and stable operation.
