Mini high-pressure pressure switch DANFOSS ACB, NC, 16 – 20 bar, automatic, SPST, solder connection 1/4" ODM

The DANFOSS ACB mini high-pressure pressure switch is the ideal solution for monitoring high-pressure values in refrigeration systems, air conditioning systems, and heat pumps . With a switching range of 16 to 20 bar, this model reliably protects against dangerous pressure peaks, thus contributing to the safety and longevity of your system .

The pressure switch is equipped with an SPST contact in NC (Normally Closed) design . This means that the circuit is closed in the idle state and opens automatically as soon as the limit pressure is reached. The automatic reset allows for immediate restart when the pressure returns to the safe range – completely maintenance-free.

The high-quality 1/4" ODM solder connection allows the switch to be permanently and leak-freely connected to copper pipes – ideal for permanent and professional installations . Thanks to its compact design, the device is ideal for tight installation situations , e.g., in mobile or industrial cooling units.

✅ Applications: Compressor protection, pressure control, high pressure shutdown
💡 Advantage: Suitable for applications with high switching frequency and limited installation space
