ABB PSR6-600-70 Soft Starter – 6.1 FLA, 208–600V AC, 120–240V Control (Compact Style)

This ABB soft starter is a compact little unit that makes motor starts smooth and easy.
The PSR6-600-70 is rated at 6.
1 full load amps, and it handles motor voltages from 208V all the way up to 600V AC – so it's super flexible for a variety of industrial motors.
Control voltage is 120–240V AC, which is standard for most panels and control circuits.

The idea behind a soft starter is simple – instead of slamming your motor with full torque at startup, it ramps up the voltage gradually, so your motor accelerates smoothly.

That means less mechanical shock to belts, gears, and couplings, plus reduced current spikes that can trip breakers or annoy your utility company.
Basically, it keeps things gentle and prolongs equipment life.

You can mount this guy on a DIN rail or screw it directly to a panel – both options are supported.
It's compact, so it doesn't gobble up space in your enclosure, leaving room for other gear.
It does require a TA25 series overload protection relay and a DB25 series mounting kit if you're going the DIN rail route, so keep that in mind when you're ordering.

ABB is a top-tier brand in industrial controls – you're not getting a cheap knockoff.
This unit is built to last, with solid terminals, clear markings, and straightforward wiring.

The PSR series is known for reliability and ease of use – no complicated programming needed, just set your ramp time and you're good to go.

If you're setting up a new motor or upgrading an old contactor-based starter, this soft starter is a modern, efficient choice.

It's quieter, smoother, and easier on your motor than a star-delta or direct-on-line setup.

Plus, it's UL-listed and meets all the usual standards, so your inspector will be happy too.
