RSBT4025FVC1HP is a three-phase controlled soft starter designed for soft starting of scroll compressors. It features a patented auto-adaptive algorithm that automatically adapts to the compressor specifications, eliminating the need for user settings while providing optimum inrush current reduction. The unit operates at 340-440 VACrms, 50/60 Hz with a rated operational current of 25 Arms and includes integrated bypass relays, over-temperature, overcurrent, and locked rotor protection. With a ramp-up time of less than 600 ms and a maximum current limit level of 90 Arms, this soft starter is ideal for multi-compressor systems in HVAC and refrigeration applications where reliable motor starting and protection are essential.
