Description
The Daikin-McQuay 300045868 Low Pressure Switch is a refrigerant pressure control component designed to monitor suction-side conditions and initiate circuit response during low-pressure situations. It operates by sensing pressure changes within the line and opening, or closing electrical contacts based on preset limits, allowing controlled response during abnormal operating conditions. The switch is calibrated for compatibility with system requirements and responds to pressure drops affecting compressor operation. Installed in coolant circuits and control assemblies in HVAC systems, it operates as a safety control element that supports system monitoring and controlled operation of connected equipments.
