Mini high-pressure pressure switch DANFOSS ACB, NC, 19 – 23 bar, automatic, SPST, 1/4" SAE flare

The DANFOSS ACB mini pressure switch is the perfect solution for high-pressure monitoring in compact refrigeration and air conditioning systems . With a switching range of 19 to 23 bar, this switch offers reliable protection against dangerous pressure peaks – ideal for heat pumps, commercial refrigeration, and split air conditioning systems .

The integrated SPST (Single Pole Single Throw) contact in NC (Normally Closed) design ensures that the circuit remains closed in the normal state and is automatically interrupted when the preset pressure is exceeded. The automatic reset allows for smooth continued operation after pressure is released – without the need for manual resetting.

Thanks to the 1/4" SAE flare connection, the pressure switch can be quickly and easily integrated into existing refrigerant lines without soldering. The compact design allows for installation even in tight spaces – ideal for modern, space-saving HVAC systems.
