Siemens 3UG4618-1CR20 Phase Monitoring Relay - 160-690V
Siemens 3UG4618-1CR20 digital monitoring relay for 3-phase voltage.
The Siemens 3UG4618-1CR20 is a digital monitoring relay designed for three-phase voltage systems with an N conductor. It offers comprehensive protection against phase failure, incorrect phase sequence, undervoltage, overvoltage, and asymmetry, with adjustable parameters for voltage range (3x 160-690 V AC), hysteresis, OFF delay, and asymmetry percentage. The relay features one CO contact for phase correction and another CO contact for power system faults, all with screw terminal connections.
This monitoring relay is crucial for safeguarding motors and electrical equipment in industrial settings by ensuring stable and correct power supply. It finds applications in various industries including manufacturing, processing plants, and building management systems where the integrity of three-phase power is critical for operational continuity.
