SKU CH-CG9B-30WS5

Soft start controller limits inrush current to 7.8 A across 240 V or 480 V three-phase supplies with 24 V DC control

  • Soft start limits inrush current for 7.8 A motors
  • Handles 2 hp three-phase loads at 200 V AC

  • Handles 5 hp three-phase loads at 480 V AC
  • 24 V DC control voltage suits low-voltage panels

Eaton DS7-340SX009N0-N Soft Start Controller

The Eaton DS7-340SX009N0-N is a soft start controller rated for 7.8 A output current. It accepts an input voltage of 240/480 V AC and delivers the same output voltage range. The unit operates with a 24 V DC control voltage and is housed in a NEMA 1 enclosure.

Suited for three-phase motor soft starting up to 5

This controller suits installations that need reduced-voltage starting for three-phase motors rated at 2 hp for 200 V AC or 240 V AC and 5 hp at 480 V AC. It is not intended for single-phase motor loads, for applications exceeding the stated horsepower ratings, or for environments requiring an enclosure rating higher than NEMA 1.

7.8 A output current at 480 V AC three-phase

The decisive specification is the 7.8 A output current at 480 V AC three-phase, which directly determines the maximum motor size the controller can start. Match this rating to the motor nameplate full-load current to confirm suitability.

Questions about this item

What enclosure rating does the DS7-340SX009N0-N need for mounting?

The soft start controller carries a NEMA 1 rating, so it must be installed inside a clean, dry indoor enclosure that meets that standard.

Which control voltage must be supplied to the 24 V DC input before commissioning?

Apply a stable 24 V DC source to the control terminals; the unit will not start without this supply present.

What wear item should be inspected after extended motor-start cycles?

The internal bypass contacts that carry the 7.8 A run current are the primary wear component; plan periodic inspection and replacement if pitting appears.
