HVAC Compressor Pressure Switch, -0.2–32 Bar / 2–45 Bar

The SUCH HVAC compressor pressure switch monitors high and low pressure for compressor control in refrigeration and air-conditioning systems. It provides pressure adjustment ranges of -0.2–32 Bar or 2–45 Bar, depending on the model, for different system pressure requirements. The mechanical micro switch responds directly to pressure changes for reliable switching in refrigeration circuits and other fluid or gas pressure control applications.

Note: This pressure switch monitors refrigerant pressure in HVAC and refrigeration systems to support high- and low-pressure control.

Feature

• Control -0.2–32 Bar or 2–45 Bar pressure ranges to suit different low- and high-pressure control requirements.
• Set adjustable differential pressure to define the switching interval for compressor control.
• Choose automatic or manual reset to match different pressure control and restart requirements.
• Use an SPDT micro switch rated up to 250VAC for direct switching in suitable control circuits.
• Read pressure and differential settings from the scale for easier field adjustment and setup.
• Handle medium temperatures from -40°C to 120°C for refrigeration and other temperature-variable applications.
• Connect through 7/16-20UNF or G1/4 interfaces for installation with compatible refrigeration piping.
• Select IP30, IP44, or IP55 protection levels to suit different installation environments and enclosure requirements.
