Voltage Monitoring Relay G2PF400VS02 – Phase Monitoring for 3-Phase 400V Networks
The G2PF400VS02 from TELE is a reliable voltage monitoring relay from the GAMMA series for monitoring 3-phase 400V AC networks. It protects machinery, motors, pumps, and electrical systems from damage caused by phase failure, phase sequence errors, and unbalanced mains voltages.
The device continuously monitors the correct phase sequence and the failure of individual phases. In addition, the relay detects back voltages and mains unbalances, thus ensuring increased operational safety in industrial applications. A neutral conductor can also be connected if required.
Since the measuring voltage also serves as the supply voltage, no separate auxiliary voltage is required. Two potential-free changeover contacts enable direct signaling or shutdown in the event of detected fault conditions. LED indicators provide information on the supply voltage and the switching status of the relay at all times.
With a width of only 22.5 mm, the voltage monitoring relay is ideal for space-saving mounting on DIN rails in control cabinets, machine controls, and industrial automation systems.
