KP Pressure Switchs Danfoss เพรสเชอร์สวิทซ์แรงดัน

KP pressure switchs are for use in refrigeration
and air conditioning systems to give protection
against excessively low suction pressure or
excessively high discharge pressure.

KP pressure switches are also used for starting
and stopping refrigeration compressors and fans
on air-cooled condensers.

A KP pressure switch can be connected directly
to a single-phase AC motor of up to approx. 2 kW
or installed in the control circuit of DC motorsand large AC motors.

KP pressure switches are fitted with a single-pole
double-throw (SPDT) switch. The position of
the switch is determined by the pressure switch
setting and the pressure at the connector.

KP pressure switches are available
in IP30, IP44 and IP55 enclosures.
