Selectron Monitoring Relay, Three Phase, DPDT, 30 → 300V ac, DIN Rail

The Voltage monitoring system is designed for both DC and AC voltages in single phase networks. It includes features such as excess voltage monitoring, low voltage monitoring, and a window function for monitoring voltage within a specified range between minimum and maximum thresholds. Additionally, it incorporates timing mechanisms for start up suppression and tripping delay.
