Product Description
The “Freedom Series” starters 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 are available in two
rating/configuration styles — NEMA
(National Electrical Manufacturers
Association) and IEC (International
Electrotechnical Commission). The
NEMA devices are sized based on
traditional NEMA classifications and
the IEC devices on international
ratings. Internationally rated starters,
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.
Features
■ A single family of 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 combi-
nations that have to be stocked.
Fixed heater overloads 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
pressure plates with ± screws —
reduced wiring time.
■ Accessible terminals for easy
wiring. Optional fingerproof shields
available to prevent electrical shock.
■
Top located coil terminals
convenient 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 — perma-
nently marked with voltage, fre-
quency and part number. IEC sizes A
– F have non-encapsulated coils as
standard, encapsulated as optional.
■
Designed to meet or exceed NEMA,
UL, CSA, IEC, VDE, BS and other
international standards and listings.
■
American engineering and manu-
facturing — built in the U.S.A. by
Eaton Corp./Cutler-Hammer, using
the latest in statistical process
control methods to produce high
quality, reliable products.
Standards and Certifications
Certified Type 2 Coordination
Cutler-Hammer Freedom Series IEC
starters and NEMA starters are UL
Certified to achieve IEC 947 Type 2
coordination against 100,000A short
circuit fault currents. Any brand of
properly selected fuse can be used.
Type 2 coordination means that the
starter will be suitable for further use
following a short circuit fault.
ISO 9001 Certification
When you turn to Cutler-Hammer
Products, you turn to quality. The
International Standards Organization
(ISO) has established a series of
standards acknowledged by 91
industrialized nations to bring harmony
to the international quest for quality.
The ISO certification process covers 20
quality system elements in design,
production and installation that must
conform to achieve registration. The
Enclosed Control is manufactured in
our Fayetteville, NC plant, and this
facility is registered ISO 9001. This
commitment to quality results in
increased product reliability and total
customer satisfaction.
Freedom NEMA starters are designed
to NEMA standards and are extremely
rugged products built for any applica-
tion. 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 Open and in NEMA 1, 3R,
4/4X, 7/9 and 12 enclosures.
Short Circuit Protection
Fuses and Inverse-Time Circuit Break-
ers
may be selected per Article 430,
Part D of the National Electrical Code
to protect motor branch circuits from
fault conditions. If higher ratings or
settings are required to start the
motor, do
not exceed the maximum
as listed in Exception No. 2, Article
430-52.
