High Pressure Controls
In refrigeration system the High Pressure (HP) cut-off switch is a control device which is used as safety control. The compressor is stopped by cutting the power supply of the motor of the compressor whenever the discharge pressure of the compressor becomes excessive. This is necessary to prevent the possible damage of equipment.
The HP switch monitors the system for an inoperative outdoor motor, and/or a dirty/restricted condenser (outdoor) coil.
When the pressure in the system exceeds the HP switch setting, the switch will open circuit the compressor clutch and the compressor will stop circulating refrigerant. The high pressure setting of the switch must correspond to the type of refrigerant in the system. Different refrigerants require different settings.

CNT0238E Pressure Switch
The Danfoss KP7BS (Trane CNT0238E) is fully compatible with common refrigerants, including R22, R134a, R404A, and R407C. It features a manual reset function, which maximizes operational safety by requiring a technician’s inspection before restarting the system after a high-pressure trip. With silver-plated contacts that ensure stable signal output even in high-vibration environments and a compact IP44-rated housing, this pressure switch is an essential safety component for Trane and other heavy-duty industrial chiller systems.
