NEMA Contactors & Starters

Product Family Overview
Freedom Line
Vol. 2, Ref. No. [0018]
Product Description
The “Freedom Series” starters and
contactors listed in this catalog feature
a compact, space-saving design, using
state-of-the-art technology and the
latest in high strength, impact and
temperature resistant insulating
materials. Starters and contactors are
available in two rating/configuration
styles — NEMA (National Electrical
Manufacturers Association) and IEC
(International Electrotechnical
Commission). See Category 34 for IEC
Rated Contactors & Starters.
The NEMA devices are sized based on
traditional NEMA classifications and
the IEC devices on international
ratings. Internationally rated starters
and contactors, as compared to NEMA
devices, generally are physically
down-sized to provide higher ratings
in a smaller package. However,
electrical load/life ratings are
correspondingly reduced. Careful
consideration should be given to the
selection of the proper device for a
specific application. Parameters, such
as type of load, severity of duty,
electrical load/life cycles required, etc.,
must be evaluated before choosing
either the IEC or NEMA designs. Since
the IEC devices are typically smaller
than the equivalent NEMA device,
there is a cost advantage over the
NEMA starters and contactors.
Application Description
The Freedom to Choose the Right
Product for the Application
Cutler-Hammer has been supplying
quality industrial control products for
more than 100 years — the Freedom
Series of Contactors and Starters con-
tinue in this tradition. They offer some-
thing no other electrical control line in
the world can — the Freedom to
choose contactors and starters
designed to either NEMA or IEC stan-
dards from one family. There are many
difficult choices to be made today in
matching electrical control to a specific
application, but the Cutler-Hammer
Freedom Series makes it easy.
Features
Freedom Family
■ A single family of contactors and
starters suitable for application in
both the IEC and NEMA markets.
“Two lines, One family” — the best
of both worlds.
■
Adjustable Bimetallic Ambient
Compensated Overload relays with
interchangeable heater packs —
available in three basic sizes,
covering applications up to 900 hp
— reducing the number of different
contactor/overload relay combina-
tions that have to be stocked. Fixed
heater overloads are optional.
■
A full line of snap-on accessories
common to both IEC and NEMA
devices — top and side mounted
auxiliary contacts, solid-state and
pneumatic timers, etc.
■
Straight-through wiring — line lugs
at top, load lugs at bottom.
■
Horizontal or vertical mounting
on upright panel for application
freedom.
■ Screw type power terminals have
captive, backed-out self-lifting pres-
sure plates with ± screws — reduced
wiring time.
■
Accessible terminals for easy wir-
ing. Optional fingerproof shields
available to prevent electrical shock.
■
Top located coil terminals conve-
nient and readily accessible. 45 mm
contactor magnet coils have three
terminals, permitting either top or
diagonal wiring — easy to replace
European or U.S. style starters
or contactors without changing
wiring layout.
■
Encapsulated dual voltage/
frequency magnet coils —
permanently marked with voltage,
frequency and part number. NEMA
Sizes 00 – 0 have non-encapsulated
coils as standard.
■
Designed to meet or exceed NEMA,
UL, CSA, IEC, VDE, BS and other
international standards and listings.
■ American engineering — built by
Eaton Corp./Cutler-Hammer, using
the latest in statistical process
control methods to produce high
quality, reliable products.
Freedom NEMA
Freedom NEMA contactors and starters
are designed to NEMA standards and
are extremely rugged products and
built for any application. Their long
electrical/mechanical life is extended
through easy maintainability.
■
Meets and exceeds all NEMA, UL
and CSA standards.
■
Sized based on standard NEMA
classifications.
■
Designed and built for a variety of
demanding applications.
■
Easy coil change and inspectable/
replaceable contacts.
■
Adjustable/interchangeable heater
packs for flexibility.
■
Available in Open and NEMA 1, 3R,
4/4X and 12 enclosures.
The Best Keeps Getting Better
Within this catalog you will discover
many enhancements to the Cutler-
Hammer contactor and starter product
line. These enhancements demonstrate
Cutler-Hammer’s commitment to contin-
uous product improvement and total
quality. A few of the Freedom Series
product improvements are listed below.
What’s Changing
In addition, all side and top auxiliary
contacts have been revised with CEN-
ELEC markings; IEC contactors to
900 hp/460V are now available; and
a new line of IEC fixed heater starters
is being introduced: AE17/57.
