Voltage Monitoring Relay G2PU690VS20 – Monitoring of Three-Phase Networks up to 690V
The G2PU690VS20 from TELE is a voltage monitoring relay from the GAMMA series for reliable monitoring of three-phase networks. The device detects undervoltage, phase failure, and incorrect phase sequence, thereby protecting machines, motors, pumps, and industrial systems from damage due to grid faults.
The relay is suitable for 3-phase networks from 208 to 690V AC and does not require a separate auxiliary voltage, as the measuring and supply voltages are identical. The undervoltage threshold can be flexibly adjusted, while the trip delay allows for safe adaptation to different applications.
Two potential-free changeover contacts are available for signaling. Multiple LED indicators reliably provide information about the supply voltage, undervoltage fault, phase sequence fault, and the current switching status. With a compact width of only 22.5 mm, the device can be mounted on DIN rails to save space.
The robust industrial design ensures reliable operation even under demanding environmental conditions and is ideal for power distribution, motor controls, and industrial automation systems.
