ABB PSR85-600-11 Soft Starter For Three Phase Motors

The ABB PSR85-600-11 Soft Starter is a compact motor starting device from ABB’s PSR Compact Range designed for soft starting and stopping of three-phase induction motors in industrial environments, reducing inrush current and mechanical wear during startup and shutdown. Rated for 85 A and 208–600 VAC with a 24 VDC control input and 100–240 VAC control supply, it supports 50/60 Hz operation and provides motor power ratings of 22 kW at 230 VAC, 45 kW at 400 VAC, and 55 kW at 500 VAC. It offers soft-start and soft-stop functions (voltage ramp), internal bypass, and a panel-mount form factor with IP10/NEMA 1 protection. Optional FieldBusPlug enables communication, and the unit is certified for CE, UL, and CSA. Typical uses include conveyors, pumps, compressors, fans, HVAC, and other manufacturing equipment where reducing inrush and wear improves reliability; common replacements include ABB PSR85-600-70, PSE105-600-70, and PSTX105-600-70.
