Siemens 3UG4616-1CR20 Phase Monitoring Relay
Siemens 3UG4616-1CR20 Phase Failure and Sequence Monitoring Relay.
The Siemens 3UG4616-1CR20 is a digital monitoring relay designed for phase failure and sequence monitoring in 3-phase systems. It operates with a voltage range of 160-690V (phase-to-phase) and has a 3x 90-400V range for undervoltage and overvoltage detection. This relay features adjustable hysteresis (1-20V) and time delays (0-20s) for undervoltage and overvoltage. It includes one CO contact for undervoltage and one CO contact for overvoltage, utilizing screw terminals. Please note, this product is phase-out, with 3UG5616-1CR20 being the preferred successor.
This monitoring relay is crucial for protecting sensitive three-phase equipment, such as motors, pumps, and compressors, from electrical disturbances like phase loss, incorrect phase rotation, undervoltage, and overvoltage. It is widely used in industrial facilities, manufacturing plants, and building services to ensure equipment longevity and operational safety.
