  • Operates on 110–230 V AC control voltage

Eaton DS7-342SX009N0-N soft start controller

The Eaton DS7-342SX009N0-N is a soft start controller rated for 9 A at 240/480 V AC. It limits inrush current on three-phase motors up to 5 hp at 480 V AC or 2 hp at 200-240 V AC. The unit accepts a control voltage of 110-230 V AC and mounts in a NEMA 1 enclosure. It suits panel builders and maintenance teams fitting motor starters in industrial cabinets.

Suits installers wiring 200-480 V three-phase

This controller fits applications where a 9 A soft start reduces mechanical stress on belts, couplings and driven equipment. It will not suit single-phase loads, DC circuits or motors exceeding the listed horsepower ratings at the stated voltages. Buyers needing higher current, different control-voltage ranges or outdoor-rated enclosures should look at other devices.

9 A rated current at 240/480 V AC three-phase

The 9 A output current at 240/480 V AC is the decisive figure for matching the controller to the motor full-load current. Verify the motor nameplate amperage against this rating before purchase.

Questions about this item

How much heat does the DS7-342SX009N0-N dissipate when running continuously at 9 A?

The controller is rated for 7.8 A output at 480 V AC; continuous operation at the 9 A nameplate will increase losses, so allow adequate enclosure ventilation.

What control-voltage supply must I already have to operate the DS7-342SX009N0-N?

A 110-230 V AC source is required for the control circuit before the soft-starter can function.

Will the DS7-342SX009N0-N start a 5 hp motor on my existing 480 V three-phase line?

Yes — it is rated for 5 hp at 480 V AC three-phase, matching the 7.8 A output current.
