ABB | PSR COMPACT SOFTSTARTER
Product overview
The ABB PSR6-600-70 is a compact softstarter for small three-phase motors, rated 6.8A under IEC conditions and 3kW at 400V for normal starting duty. It uses a controlled voltage ramp for soft starting and stopping, with built-in bypass contacts for running operation. The exact ABB ordering reference is 1SFA896104R7000.
Key features
- 208-600V AC main circuit and 100-240V AC control supply
- Two-phase control with front-mounted potentiometers
- Built-in bypass and a normally open RUN signal relay
- DIN-rail or screw mounting; compatible motor-starter connection kit, cooling fan and fieldbus adapter

Motor power depends on supply voltage and starting duty. The 6.8A value is the IEC operational rating; UL motor ratings use their own voltage-specific horsepower and FLA tables. Provide coordinated short-circuit and overload protection externally. This softstarter is not a variable-frequency drive.
Accessories and installation
| Connection Kit | PSR16-MS116 — 1SFA896211R1001 |
|---|---|
| Cooling Fan | PSR-FAN3-45A — 1SFA896311R1001 |
| Fieldbus Adapter | PS-FBPA — 1SFA896312R1002 |
The PSR16-MS116 connection kit fits PSR3-PSR16 with an MS116 or MS132 manual motor starter. The kit does not include the motor starter. PSR-FAN3-45A is the matching auxiliary fan for PSR3-PSR45. PS-FBPA is an adapter with cable; a matching protocol-specific fieldbus interface is a separate component. Each selected accessory is one item per softstarter and has its own ABB ordering reference.
Typical applications
- Small pump and fan starting
- Compact conveyor and compressor motor starters, sized for the actual load and starting duty
- Industrial control panels requiring soft start and soft stop with fixed-speed running
