Product Description
Eaton’s Cutler-Hammer
Technologies (
Reduced Voltage Soft Starters is very
compact, multi-functional, easy to
install and easy to program. Designed
to control acceleration and
deceleration of 3-phase motors, the
line is available for current ranges
from 12 amp all the way through 1000
amp applications and is suitable for
mounting in motor control centers or
in enclosed control (NEMA 1, 4, 4X and
12) applications.

Application Description
The S801 line of IT. Soft Starters is
designed to be the smallest, most
compact soft starter in the market
today. With this small size, it can easily
fit in place of existing soft starter
designs, wye-delta starters or acrossthe-line NEMA and IEC starters. This
feature allows easy retrofits of existing
Motor Control Centers or Enclosures
and saves the expense of replacing
existing structure or adding a new one
to house a soft starter.
The product is designed to work with
3-phase motors in a Delta (3-lead)
configuration. The S801 works with all
motors from fractional horsepower up
to motors requiring 1000 amps of
steady state current. The built-in overload (in ranges from 12 – 1000 amps)
and run bypass contactor make installation and setup quick and easy. The
overload also offers some advanced
protective functions to give additional
motor protection.
With the pump control option, it is the
number one soft starter available for
pumping applications. The unique soft
stopping control provides a smooth
transition for stopping a motor and
eliminates the “water-hammer” effect
that can damage pipes, valves and
pumps.

Benefits
Reduced wear on belts, gears,
■
chains, clutches, shafts and
bearings
■
Allows for controlling the inrush
current to the motor
■
Reduced inrush current leads to
more stable power grid and can
lower peak demand charges
Elimination of water-hammer in
■
pumping applications
■
Less shock to product on conveyor
lines and material handling gear
■
24V DC control enhances personnel
and equipment safety
Operation
Overload Functionality
Overtemperature
Protects the device from overheating.
Starter will shutdown at 110°C.
Jam
Selectable protective feature, unit trips
to prevent damage to motor during
normal run.
Stall
Selectable protective feature, unit trips
to protect system in event motor can
not get to rated speed in the defined
ramp period.
Phase Loss
Selectable protective feature, trips
under voltage loss condition to any
phase.
Phase Reversal
Selectable protective feature, trips
when phase rotation is something
other than A-B-C.
Kick Start
Selectable feature which provides a
current “kick” of up to 550% of full load
current for 0 to 2.0 seconds. This
provides the additional torque required
at startup to break free a motor.
Ramp Start
Provides a constant increase in torque
to the motor.
Current Limit Start
Limits the maximum current available
to the motor during the startup phase.
Soft Stop
Allows for a controlled stopping of a
frictional load.
Shorted SCR Detection
Monitors for shorted SCR in the power
polls.

Starting Characteristics
Kick Start
Provides an initial boost of current
to the motor to help break free the
rotor and start spinning the motor.
0 – 85% of locked rotor torque.
■
■
0 – 2.0 seconds duration.
Ramp Start
The most commonly used form of soft
start. This allows you to set the initial
torque value (of the ramp) and then
raises it to full voltage conditions.
■
Adjustable initial torque =
0 – 85% of locked rotor torque.
■
Adjustable ramp time =
.5 – 180 seconds (can be extended
with factory modification).

Current Limit
This mode of soft starting is used
when it becomes necessary to limit the
maximum starting current due to long
start times or to protect the motor.
■
Maximum current of 0 – 85% locked
rotor current.
■
Adjustable ramp time =
.5 – 180 seconds (can be extended
with factory modification).
Soft Stop
Used when an extended coast-to-rest
period is desired. Often used with high
friction loads where a sudden stop
may cause system or product damage.
■
Stop time = 0 – 60 seconds.
