Mini high-pressure pressure switch DANFOSS ACB, NO, 19 – 23 bar, manually reset, SPDT, 1/4" SAE flare

The DANFOSS ACB mini high-pressure pressure switch was specifically developed for demanding high-pressure applications in refrigeration systems, air conditioning systems, heat pumps , and industrial cooling processes . Thanks to its compact design and high functional reliability, it is ideal for pressure monitoring in safety-critical systems.

With a switching range of 19 to 23 bar, the pressure switch offers reliable protection against overpressure in refrigerant circuits . The SPDT changeover contact with NO (Normally Open) function activates the circuit only when the pressure is exceeded – ideal for controlling warning systems or shutdowns. The manual reset ensures maximum control and prevents accidental reactivation – an important safety feature in commercial applications.

The standardized 1/4" SAE flare connection enables solder-free, quick, and leak-proof installation into existing systems. Its robust design also allows for use in systems with limited space .
