The Siemens 7PU60 20-3NT2 Star-Delta Time Delay Relay is a high-precision timing device designed for controlling star-delta motor starting sequences. This relay ensures smooth and reliable transitions from star to delta configuration, significantly reducing inrush currents and mechanical stress on motors during startup.
Engineered by Siemens, this electronic star-delta timer is widely used in industrial automation, pumping systems, HVAC machinery, compressors, and other heavy-duty equipment where controlled motor starting is essential. With dual time-range settings of 2–20 seconds and 6–60 seconds, it provides flexible adjustment to match the motor’s torque and load conditions.
Designed to operate at 380/440V AC and compatible with both 50 Hz and 60 Hz systems, this relay is suitable for global power environments. Compliance with IS 5834 (Part III) ensures high reliability, durability, and adherence to electrical safety standards.
