Mini high-pressure pressure switch DANFOSS ACB, NC, 33 – 42 bar, automatic, SPST, solder connection 6 mm ODF

The DANFOSS ACB mini high-pressure pressure switch is designed for use in high-pressure refrigeration systems, heat pumps, and industrial air conditioning systems . With a switching range of 33 to 42 bar, this switch reliably protects against dangerous overpressure situations in the refrigerant circuit.

It features an SPST contact and NC (Normally Closed) function , meaning the circuit is closed during normal operation and automatically opens as soon as the pressure reaches the set limit. The automatic reset ensures a smooth restart of the system once the pressure returns to the safe range.

The 6 mm solder connection (ODF) enables a permanent, tight and vibration-proof connection to copper pipes – ideal for professional installations in long-lasting systems.
