Description for 3UG4617-2CR20
The 3UG4617-2CR20 Digital Monitoring Relay is an essential component for any modern electrical system, designed specifically for 3-phase supply voltage applications. With its advanced capabilities, this relay ensures optimal performance by automatically correcting phase sequences, preventing phase failures, and offering a comprehensive monitoring solution.
Operating within a voltage range of 160 to 690 V and a frequency of 50 to 60 Hz AC, it effectively protects your installations against both undervoltage and overvoltage conditions. The hysteresis setting ranges from 1-20 V, providing customizable sensitivity, while the OFF delay feature from 0-20 seconds allows for precise operation control.
Additionally, it accommodates voltage asymmetry up to 20%, ensuring reliable functionality in variable electrical environments. Featuring one changeover contact (CO) for phase correction and another for line supply faults, this relay employs a spring-type connection system for easy and secure installations.
Manufactured by Siemens in Germany, the 3UG4617-2CR20 not only meets industry standards but also delivers exceptional quality and reliability. Ideal for professionals in the electrical industry, this monitoring relay is a pivotal tool designed to enhance the safety and efficiency of your electrical systems.
