ERV-YU-V2 star delta timer relay is designed for automatic motor starting control using star-delta transition. It provides precise timing for switching between star and delta connections, helping to reduce inrush current and protect electrical equipment.
The relay features an adjustable star time range of 0.1–30 seconds and a transition (wait) time of 10–500 milliseconds, ensuring smooth and reliable switching between operating modes.
With stable performance, easy DIN rail installation, and compact design, it is widely used in motor control panels, industrial automation systems and power distribution applications.
Star Time: 0.1–30s
Transition Time: 10–500ms
