Danfoss Pressure Switches, 7.5 Bar

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 condensersA 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 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.Features: Ultra-short bounce time thanks to snap-action function (reduces wear to a minimum and increases reliability) Manual trip function (electrical contact function can be tested without the use of tools) Types KP 6, KP 7 and KP 17 with fail-safe double bellows element Vibration and shock resistant Compact design Fully welded bellows element High reliability both electrically and mechanically Approvals: CE-marked in accordance with: – LVD 2006/95/EC (EN 60947-1, EN 60947-4-1, EN 60947-5-1) PED 97/23/EC, category IV (EN 12263): KP 1, KP 2, KP 6, KP 7 and KP 17 Underwriters Laboratories Inc., UL listed China Compulsory Certificate, CCC Ship Approvals: Germanischer Lloyd, GL Det Norske Veritas, Norway, DNV Registro Italiano Navale, RINA Bureau Veritas, BV Lloyd's Register, LR Russian Maritime Register of Shipping, RMRS Specifications: Ambient temperature: 40 – 65 °C (80 °C for max. 2 hours).
