Voltage Monitoring Relay G2PM400VSY20 24–240V AC/DC – Multifunctional Grid Monitoring for 3-Phase Systems
The G2PM400VSY20 24–240V AC/DC from TELE is a multifunctional voltage monitoring relay from the GAMMA series for monitoring 3-phase grids with 400V AC. The device reliably protects machines, motors, and electrical systems from grid faults and increases operational safety in industrial applications.
The monitoring relay detects undervoltage, phase failure, phase sequence errors, and asymmetrical voltage conditions. Additionally, a neutral conductor can be connected, which also allows for the detection of neutral conductor interruptions. Various monitoring functions, such as undervoltage monitoring or window monitoring, can be easily selected via a rotary switch.
The adjustable tripping delay of 0.1 to 10 seconds prevents nuisance tripping due to short-term grid fluctuations. Multiple LED indicators provide information on the operating status, fault type, and relay status at all times.
With two potential-free changeover contacts and a compact width of only 22.5 mm, the device is ideal for DIN rail mounting in control cabinet construction, mechanical engineering, and industrial automation systems.
