Product Description
Non-reversing
Three-phase, full voltage magnetic
starters are most commonly used to
switch AC motor loads. Starters con-
sist of a magnetically actuated switch
(contactor) and an overload relay
assembled together.
Reversing
Three-phase, full voltage magnetic
starters are used primarily for revers-
ing of 3-phase squirrel cage motors.
They consist of two contactors and a
single overload relay assembled
together. The contactors are mechani-
cally and electrically interlocked to
prevent line shorts and energization
of both contactors simultaneously.
Features
■ Bimetallic Ambient Compensated
Overload relays — available in three
basic sizes covering applications up
to 900 hp — reducing number of
different contactor/overload relay
combinations that have to be
stocked.
These overload relays feature:
❑ Selectable Manual or Automatic
Reset operation.
❑ Interchangeable heater packs
adjustable ±24% to match motor
FLA and calibrated for 1.0 and
1.15 service factors. Heater packs
for smaller overload relay will
mount in larger overload relay —
useful in derating applications
such as jogging.
❑ Load lugs built into relay base.
❑ Single-phase protection, Class 20
or Class 10 trip time.
❑ Overload trip indication.
❑ Electrically isolated NO-NC con-
tacts (pull RESET button to test).
■ The C396 is a self-powered, robust
electronic overload designed for
integrate use with Freedom NEMA
contactors.
❑ Tiered feature set to provide cov-
erage specific to your application.
❑ Broad 5:1 FLA range for maxi-
mum flexibility.
❑ Coverage from 0.05 – 1500 Amps
to meet all your needs.
■ Long life twin break, silver cadmium
oxide contacts — provide excellent
conductivity and superior resistance
to welding and arc erosion. Gener-
ously sized for low resistance and
cool operation.
■ Designed to 3,000,000 electrical
operations at maximum hp ratings
up through 25 hp at 600V.
■ Steel mounting plate standard on all
open type starters.
■ Wired for separate or common
control.
Non-reversing
■ Holding circuit contact(s) supplied
as standard:
❑ Sizes 00 – 3 have a NO auxiliary
contact block mounted on right-
hand side (on Size 00, contact
occupies 4th power pole position
— no increase in width).
❑ Sizes 4 – 5 have a NO contact
block mounted on left side.
❑ Sizes 6 – 7 have a 2NO/2NC
contact block on top left.
❑ Size 8 has a NO/NC contact block
on top left back and a NO on top
right back.
Reversing
■ Each contactor (Size 00 – 8)
supplied with one NO-NC side
mounted contact block as standard.
NC contacts are wired as electrical
interlocks.
