Siemens 3UG4614-1BR20 Phase Monitoring Relay - Screw Terminal
Siemens 3UG4614-1BR20 Phase Failure and Sequence Monitoring Relay.
The Siemens 3UG4614-1BR20 is a digital monitoring relay designed for phase failure and sequence monitoring in 3-phase systems. It operates with voltages from 3x 160 to 690 V at 50 to 60 Hz. This relay detects asymmetry up to 20%, monitors phase sequence, and phase failure. It also features undervoltage monitoring (160-690 V) with an adjustable hysteresis of 1-20 V, and both ON and OFF delays adjustable from 0-20 seconds. The unit includes two change-over contacts and utilizes screw terminals for connection.
This relay is crucial for protecting motors and other three-phase equipment from damage caused by incorrect phase rotation, loss of a phase, or voltage fluctuations. It is widely used in industrial machinery, pump controls, conveyor systems, and HVAC applications to ensure proper and safe operation.
