Product Description
Eaton’s revolutionary design
for soft starters is shown in
the S801+ and S811+ soft
starter products that are
members of the Intelligent
Technologies (IT.) family of
products. These reduced
voltage soft starters are
the most compact, multi-
functional, easy-to-install
products on
the market. Their
superiority
begins with the
control package, which
features 24 Vdc control,
onboard Digital Signal
Processor (DSP), and use of a
low impedance run contactor,
all of which contribute to the
IT. soft starter’s safety,
advanced functionality and
compact size.
Designed to control
acceleration and deceleration
of three-phase motors,
products are available from
11 to 1000 amps and are
suitable for mounting in a
variety of enclosures
including Type 1, 12, 3R, 4,
4X and 7/9.

Features and Benefits
●
Mechanical stress on
system
●
Reduced wear on belts,
gears, chains, clutches,
shafts and bearings. You
can get up to 2–6 times
the life on standard belts
by switching to a soft
starter
●
Elimination of water-
hammer in pumping
applications extends
component life and
helps limit leakage in
system
●
Lower shock to product
on conveyor lines and
material handling gear
●
Able to catch motors
and fans on the fly and
control their acceleration
●
Electrical system
improvements
●
Limits the peak inrush
current as required by
many local codes
●
Helps to eliminate sags
on the plant electrical
grid when starting large
loads, thus avoiding
brownout conditions
●
24 Vdc advantages
●
Offers improved
personnel safety by
eliminating the need for
120 Vac in the enclosure
●
Soft starter able to ride
through 50% voltage
conditions indefinitely
due to 24 Vdc power
supply and 0% for up to
100 mS
●
690V option available on
180A ratings and larger
