KP-E

KP-E pressure switches for use in refrigeration and air conditioning systems are equipped with SPDT gold plated contacts and stainless steel bellows.

Versions with manual reset act as pressure limiter (pressure sensing control which is intended to keep a pressure below or above a predetermined value during normal operating conditions and may have a provision for setting by the user). Versions with automatic reset act as pressure operating control (pressure sensing control set at high or low pressure between which limits the switch is normally intended to operate). The high-pressure switches are equipped with failsafe double bellows, whereas the low pressure switches are equipped with reduced bellow travel to enhance bellows lifetime. KP-E pressure switches are used to limit or regulate the pressure against excessively low suction pressure or excessively high discharge pressure.

The units are designed to operate in explosive zones acc. to 2014/34/EU, Atex directive, explosive zone 2, surface equipment, category 3.

KP-E pressure switches are suitable for HCFC, HFC and HC refrigerants.
