The E1YF400VT01 0.85 is a voltage monitoring relay designed to ensure the stability and safety of three-phase systems by monitoring each phase against the neutral wire. Operating at a nominal voltage of 400/230V AC, it features a fixed switching threshold set at 195.5V (L-N) with a hysteresis of approximately 5%, providing consistent undervoltage detection. The relay includes a test function, enabling manual disconnection of the output relay for system testing purposes. Equipped with a single changeover contact rated at 250V AC and 5A, the E1YF400VT01 0.85 offers reliable switching capabilities. Its compact 17.5mm DIN-rail mountable design allows for efficient installation in control panels. LED indicators provide clear visual status updates: green LEDs for supply voltage presence on each phase (L1, L2, L3) and a yellow LED indicating the relay output status. Engineered for precision and durability, the E1YF400VT01 0.85 is an ideal solution for safeguarding three-phase systems against undervoltage conditions.
