Voltage Monitor, E1YF400V01 0.85

The E1YF400V01 0.85 is a voltage monitoring relay designed for three-phase systems, ensuring equipment protection by monitoring undervoltage conditions. Operating at a nominal voltage of 400/230V AC, it monitors each phase against the neutral wire. The relay has a fixed switching threshold set at 195.5V (L-N) with a hysteresis of approximately 5%, providing consistent undervoltage detection. It features a tripping delay of approximately 200 milliseconds to prevent nuisance tripping. Equipped with a single changeover contact rated at 250V AC and 5A, the E1YF400V01 0.85 offers reliable switching capabilities. Its compact 17.5mm DIN-rail mountable design allows for efficient installation in control panels. A yellow LED indicator provides a clear visual status of the relay output, facilitating easy monitoring. Engineered for precision and durability, the E1YF400V01 0.85 is an ideal solution for safeguarding three-phase systems against undervoltage conditions. - Monitoring relay series ENYA - Voltage monitoring 3-phase - Undervoltage monitoring - Measuring voltage = supply voltage - Switching threshold fixed U x 0,85 - Supply voltage 3x 400/230V AC - Voltage monitoring in accordance with VDE 0108-100 and VDE 0100-718 - 1 changeover contact - Width 17.5mm - Installation type
