KP

KP pressure switches 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 motors and large AC motors. KP pressure switches are fitted with a singlepole 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.

KPU

The KPU pressure switches are designed for use in refrigeration and air-conditioning systems to protect the systems from excessively low suction pressure or too high discharge pressure. They can also be applied to start and stop compressors and the fans of air-cooled condensers. The KPU pressure switches, in single and dual versions cover a comprehensive range of applications, and are designed for use with HCFC and non-flammable HFC refrigerants.
