ABB PSR16-600-70 Soft Starter

The ABB PSR16-600-70 Soft Starter is a compact motor starting device that minimizes electrical inrush and mechanical stress during startup and shutdown in industrial motor control and automation systems. It is commonly applied in pumps, conveyors, compressors, fans, and HVAC equipment where smooth acceleration and deceleration boost equipment reliability. Key specifications include a rated operational current of 16 A, rated operational voltage 208–600 VAC, rated control supply 100–240 VAC, and a 24 VDC control circuit, with soft-start and soft-stop functions (voltage ramp) and an internal bypass. The unit powers three-phase induction motors up to 4 kW at 230 VAC and up to 7.5 kW at 400–500 VAC, with IP20/NEMA 1 protection, mounting on DIN rail or panel, ambient operating range −25°C to +60°C, and storage range −40°C to +70°C; FieldBusPlug is available as an option, and it carries CE, UL, and CSA certifications. It is part of ABB's PSR Compact Range and serves as a replacement for models such as PSR16-600-11, PSR25-600-70, and PSE18-600-70.
