Data sheet Pressure controls, Type KP, with …

1 Danfoss A/S, 12 - sheetPressure controls, type kp , with enclosure IP 33 or IP 44KP Pressure controls are for use in refrigerationand air conditioning systems to give protectionagainst excessively low suction Pressure orexcessively high discharge Pressure controls are also used for startingand stopping refrigeration compressors and fanson air-cooled Pressure controls are fitted with a single-poledouble-throw (SPDT) switch. The position of theswitch is determined by the Pressure controlsetting and the Pressure at the Pressure controls are available in IP 33 andIP 44 Ultra-short bounce timesReduces wear to a minimum and increasesreliability. Manual controlElectrical contact function can be testedwithout the use of tools.

10 KP 7 and KP 17 have a double bellows: an outerbellows and a regulating bellows. When systempressure exceeds the set value, the KP willautomatically stop the plant. The double bellowssystem prevents loss of charge in the event ofbellows rupture in the outer bellows will cause thecontrol cut-out Pressure to fall to about 3 barunder the set value, thus providing a with designation W or AW cut in againautomatically when the Pressure has fallen tothe set value minus the with designation B or AB can be cut inmanually with the external reset button whenthe Pressure in KP 1 has raised bar aboveset value and in KP 7 has fallen 4 bar under theset with designation S or AS can be cut inmanually with the internal reset arm when thepressure has fallen 4 bar under the set KP Pressure controls, including those whichare DIN-approved.
