Great reliability and long service life

The KP pressure switches from Danfoss are optimized for light and heavy commercial refrigeration providing excellent protection against low suction pressure or high discharge pressure. KP pressure switches are used for starting and stopping refrigeration compressors and fans on air-cooled condensers.

KP thermostats are single-pole, double-throw (SPDT) temperature operated electric switches. KP is used for regulation, but can also be applied in safety monitoring systems.

With the KP pressure switches you get great reliability and long service life due to the snap-action function ensuring ultra-short bounce times. The KP pressure switch is available with IP30, IP44 and IP55 enclosures for appropriate protection based on the application.
