Siemens Industrial Controls 3UG5616-1CR20 Digital Voltage Monitoring Relay

The Siemens Industrial Controls 3UG5616-1CR20 Digital Voltage Monitoring Relay operates as a small yet precise equipment to track three-phase voltage systems for overvoltage, under voltage, and phase conditions. It protects HVAC system components, including compressors and pumps, and motors, through its continuous voltage level monitoring function. The relay protects systems that operate in chillers and air-handling units, and refrigeration systems by monitoring voltage to prevent damage from anomalies. The equipment provides fast installation through DIN rail mounting and supports flexible operation. The main advantages of this component are shorter equipment downtime combined with longer system longevity and increased energy efficiency, which makes it necessary for contemporary HVAC control panels used in commercial and industrial settings.
