Mini high-pressure pressure switch DANFOSS ACB, NC, 16 – 20 bar, automatic, SPST, 1/4" SAE flare

The DANFOSS ACB mini high-pressure pressure switch was specifically developed for use in compact refrigeration and air conditioning systems , where reliable and precise monitoring of the high-pressure range is essential. With a switching range of 16 to 20 bar, this model offers effective protection against overpressure – for example, to protect compressors or piping systems.

Equipped with a normally closed (NC) SPST contact, the circuit is normally closed and opens automatically when the preset pressure is exceeded. The automatic reset ensures that the system is immediately operational again after pressure is relieved – without any manual intervention.

Thanks to the standardized 1/4" SAE flare connection, the pressure switch can be installed quickly, safely, and without soldering . The compact design allows for easy integration even in limited space , such as in mobile refrigeration systems or cramped installation situations.

✅ Ideal for : compressor protection, high pressure shutdown, commercial refrigeration, heat pumps
💡 Particularly advantageous for cramped systems with high switching frequency
