KPU pressure switches are designed to be contractor friendly and used in refrigeration and air conditioning systems to protect the systems from excessively low suction or too high discharge pressure. They can also be applied to start and stop compressors and the fans of air-cooled condensers. KPU pressure switches, in single and dual versions, cover a comprehensive range of applications and are designed for use with fluorinated and non-aggressive refrigerants. Most KPU pressure controls can be used with R-410A systems.

Features & Benefits

• Snap Action Electrical Contacts Minimize Chatter, Bounce and Wear and Ensure Long Term Electrical and Mechanical Reliability
