Eaton S801+ Series Soft Starter – Product Spotlight

Eaton’s S801+ Series Soft Starters are designed to control acceleration and deceleration of three-phase motors. These reduced voltage soft starters are compact, multi-functional, easy to install and easy to program. The line is available for current ranges up to 1,000 A.

Because of the S801+’s small design, it can easily fit in place of existing soft starter designs, wye-delta starters or across-the-line NEMA and IEC starters. As such, the starter is an ideal solution for retrofits of existing motor control centers or enclosures, saving the end user the expense of replacing existing structure or adding a new one to house a soft starter.

Designed to work with three-phase motors in a delta configuration, the S801+ works with all motors from fractional horsepower up to motors requiring 1,000 A of steady-state current.

The S801+ series features an advanced range of overload protection features to maintain the health of equipment in the system:

  • Overtemp – the starter will automatically shut down at 100°C to protect equipment from overheating
  • Stall – the starter will trip automatically if the motor can’t reach its rated speed in the the defined ramp period
  • Jam – the starter will trip automatically to prevent damage to the motor as it tries to normally run with a jammed load
  • Phase Loss – the starter will trip under voltage loss conditions to any phase
  • Phase Reversal – the starter will trip when phase rotation is something other than A-B-C

Stall, Jam, Phase Loss and Phase Reversal are all selectable protective features.

S801+ soft starters also feature a kick start function (current “kick” up 550 percent the full load current for 0 to 2 seconds, providing additional torque to break free a motor), ramp start operation, current limit start, soft stop (controlled stopping of a frictional load), and shorted SCR detection.

These soft starters are available in five different frame sizes in either 230, 380-400 or 440 VAC specification.
