Siemens 3UG4617-1CR20 Phase Correction Monitoring Relay - Screw
Siemens 3UG4617-1CR20 3-Phase Voltage and Phase Correction Relay.
The Siemens 3UG4617-1CR20 is a digital monitoring relay for 3-phase line voltage, featuring automatic phase sequence correction. It monitors phase failure, undervoltage, and overvoltage within the 3x 160 to 690 V range at 50 to 60 Hz. This relay offers adjustable hysteresis (1-20 V) for voltage monitoring, an OFF delay of 0-20 seconds, and asymmetry detection up to 20%. It provides one change-over contact for phase correction and another for power system faults, using screw terminals for connection.
This relay is essential for applications requiring not only monitoring but also automatic correction of phase sequence, crucial for motor longevity and operational efficiency. It protects against voltage fluctuations and phase loss, ensuring system stability.
