Mini high-pressure pressure switch DANFOSS ACB, NC, 21 – 28 bar, automatic, SPST, 1/4" SAE flare

The DANFOSS ACB mini high-pressure pressure switch is a compact and powerful solution for monitoring high-pressure areas in refrigeration, air conditioning, and heat pump systems . With a switching range of 21 to 28 bar, this model is ideal for protecting against overpressure in refrigerant circuits.

The switch is equipped with an SPST contact and operates in NC (Normally Closed) mode . This means the circuit is normally closed and opens automatically as soon as the set pressure is exceeded. The automatic reset restores normal operation when the pressure drops.

The standardized 1/4" SAE flare connection enables simple, secure, and solder-free installation. Thanks to its compact design, this switch is particularly suitable for space-critical applications in commercial refrigeration technology.
