PSR45-600-70 Compact Soft Starter 45A 208-600V IP20 | ABB

The Original New ABB PSR45-600-70 (1SFA896111R7000) is a compact, three-phase soft starter from the ABB PSR series, engineered for smooth motor starting and stopping in light to medium industrial applications. Rated at 45 A with a 208–600 V AC wide-range input, this soft starter reduces mechanical and electrical stresses during motor starts by limiting inrush current to 4 × Ie for 6 seconds, compared to 6–8 times for direct-on-line (DOL) starting. Featuring an IP20 enclosure, built-in bypass, and three front-panel potentiometers for easy adjustment, the PSR45-600-70 provides a cost-effective, space-saving solution for pumps, fans, conveyors, compressors, and other motor control applications.
