Mini high-pressure pressure switch DANFOSS ACB, NC, 24 – 31 bar, automatic, SPST, 1/4" SAE flare

The DANFOSS ACB mini high-pressure pressure switch is a compact and reliable high-pressure switch for automatic monitoring and control of refrigeration, air conditioning, and heat pump systems . With a switching range of 24 to 31 bar, this model offers ideal protection against overpressure situations in high-pressure refrigeration circuits.

Equipped with an SPST switch contact with NC (Normally Closed) function, the device automatically interrupts the circuit as soon as the set pressure is exceeded. The automatic reset allows it to be restarted once the pressure has returned to normal – without any manual intervention.

Thanks to the 1/4" SAE flare connection, installation is quick and easy without soldering. The robust and compact design allows for use even in tight spaces.
