The Danfoss 17111051 is a KP1 pressure switch, a vital component for regulating and protecting refrigeration and air conditioning systems. Designed primarily for low-pressure applications, this switch automatically controls the system by responding to changes in pressure, effectively safeguarding compressors against damage from excessively low suction pressure. Its robust and compact design ensures reliable performance and a long operational life. The KP1 features a wide regulating range and an adjustable differential, allowing for precise control tailored to specific system requirements. Equipped with a single-pole double-throw (SPDT) contact system, it offers versatile electrical connection options for control circuits, alarms, or other signaling functions.
