KP-E pressure switches for use in refrigeration and air conditioning systems with hydrocarbons are equipped with SPDT gold plated contacts and stainless steel bellows. The high pressure switches are equipped with failsafe double bellows, whereas the low pressure switches are equipped with reduced bellow travel to enhance bellows life time. The switches are used to protect against excessively low suction pressure or excessively high discharge pressure. KPE pressure switches for hydrocarbons are equipped with 1/4 in. solder connection to ensure a hermetic installation Contact Rating: Ci=10 nF. Ii=0.1 A. Li=0.1 mH. Ui=30 V.
