ABB PSR Series Solid-State Softstarter, 600V AC

The ABB PSR Series softstarter delivers two-phase control soft start and stop through a voltage ramp, built for small three-phase motors with nominal currents from 3...105 A. Operating voltage spans 208...600 V AC with a control voltage of 100...240 V AC at 50/60 Hz, and the compact design includes a built-in bypass for easy installation and energy savings during full-speed operation. A RUN and TOR signal are available from a relay output in NO (normally open) state, making the PSR Series a reliable, code-conscious choice for professional motor control applications that call for smooth, low-shock starting and stopping. As ABB's most compact softstarter platform with basic functionality and values, the PSR Series is designed to manage up to 100 starts per hour, giving installers a dependable option for frequent-cycling equipment.

Key Features

  • Operating Voltage: 208...600 V AC operational range supports a wide span of three-phase motor installations.
  • Control Voltage: 100...240 V AC at 50/60 Hz for flexible control power compatibility across facilities.
  • Two-Phase Soft Start/Stop: Voltage-ramp control smooths motor starting and stopping to reduce mechanical and electrical stress on connected equipment.
  • Built-In Bypass: Simplifies installation and improves energy efficiency by bypassing the softstarter once the motor reaches full speed.
  • Relay Output Signals: RUN and TOR signals are available from a relay output in NO (normally open) state for straightforward status monitoring.
  • Adjustable Ramp and Time: Three front-mounted potentiometers allow easy, tool-free setting of start/stop ramp and time without external programming.
  • MMS Compatibility: Mechanical connection kits are available for combining the PSR Series with ABB manual motor starters (MMS) in a single assembly.
  • Fieldbus-Ready: Fieldbus communication can be enabled with an external adaptor and Fieldbus plug for integration into automated control systems.
  • Motor Current Range: Suitable for small three-phase motors with nominal currents from 3...105 A, supporting up to 100 starts per hour.

ABB PSR30-600-70 – Frequently Asked Questions

1) What motor size and voltage will the ABB PSR30-600-70 softstarter handle?
The PSR30-600-70 is one model in ABB's PSR Series, a platform covering nominal motor currents from 3 to 105 A on three-phase supplies between 208 and 600 V AC. Control power is separate: 100 to 240 V AC at 50/60 Hz. Size the unit to the motor's nameplate full-load amps and confirm your line voltage falls inside the 208 to 600 V window before ordering.
2) Do I need a separate bypass contactor with an ABB PSR softstarter?
No. The PSR Series has a bypass built in. Once the motor reaches full speed the SCRs are bypassed internally, so you are not adding an external bypass contactor to the panel and you are not carrying the heat losses of the thyristors during run. That keeps the panel footprint down and cuts energy waste at full speed.
3) Is a softstarter like the ABB PSR the right choice, or do I need a VFD?
A softstarter and a VFD solve different problems. The PSR Series ramps voltage on two phases to bring a motor up and down smoothly, which cuts inrush and mechanical shock on pumps, fans, compressors and conveyors. It does not control speed once running, and it does not run the motor at anything other than line frequency. If you only need to stop slamming the driveline and knocking the service on start, the softstarter is the smaller, simpler box. If the process needs variable speed or flow control while running, you need a drive instead.
4) How often can a PSR softstarter start the motor per hour?
Up to 100 starts per hour. That makes the PSR Series workable on frequent-cycling loads like transfer pumps and conveyors that restart repeatedly through a shift. If your duty cycle pushes past that, the PSR platform is not the right pick.
5) Does the ABB PSR softstarter need programming software to set up?
No software and no keypad. Three potentiometers on the front face set the start ramp, the stop ramp, and the time. You set them with a screwdriver on the job, which is why this platform suits panel builders and maintenance electricians who do not want a laptop in the enclosure to commission a starter.
6) What status signals can I wire back to my control panel or PLC from a PSR softstarter?
RUN and TOR (top of ramp) signals come off a relay output in the normally open state. That gives you a dry contact for run confirmation and for the point where the ramp completes, which is what you would interlock to a downstream valve, a pilot light, or a PLC input.
7) Can I combine the ABB PSR softstarter with a manual motor starter in one assembly?
Yes. ABB offers mechanical connection kits that couple the PSR Series directly to ABB manual motor starters (MMS), so the short-circuit and overload device and the softstarter mount as one block on the rail. The kits are ordered separately from the softstarter itself.
8) Can a PSR softstarter talk to a fieldbus network?
Not on its own. Fieldbus communication on the PSR Series requires an external adaptor plus a Fieldbus plug, both ordered in addition to the starter. Out of the box the unit is hardwired control with pot settings and the RUN/TOR relay output, so budget the adaptor into the order if the panel is going onto an automated network.
9) What exactly does two-phase control mean on an ABB PSR softstarter?
Two-phase control means the voltage ramp is applied on two of the three motor phases while the third is passed straight through. You still wire all three phases through the unit, and it still gives you a controlled start and a controlled stop. It is the simpler, more compact approach ABB uses on the PSR platform, which is their most basic softstarter line, as opposed to three-phase controlled units with more functionality.
10) Where can I get the full technical data for the ABB PSR30-600-70?
ABB publishes a spec sheet for the PSR Series covering the detailed electrical data, and it is linked in the product specifications for this softstarter. Use it to confirm frame size, terminal capacity, and the current rating of the specific model against your motor nameplate.
