ABB | PSR
Product overview
The ABB PSR45-600-70 softstarter is rated 45A IEC and 22kW at 400V for normal in-line starting duty. It operates on a three-phase 208-600V AC supply with 100-240V AC control power and built-in bypass. ABB ordering reference: 1SFA896111R7000.
Key features
- Controlled soft start and soft stop with front potentiometers
- Built-in bypass reduces running losses
- Compact motor starter installation with separately ordered matching accessories

Power depends on supply voltage and starting duty. IEC operational current and UL FLA are separate ratings. External coordinated short-circuit and overload protection are required. Connection kits do not include the motor starter. The fieldbus adapter requires a separate protocol-specific interface.
