Product Family Overview
Freedom Line
Vol. 2, Ref. No. [0019]
Freedom Enhancements
Accessible Power Terminations to
Facilitate Installation
The 65 mm contactor housing has
been completely redesigned to open
up the line/load terminal access area,
allowing better visibility when wiring.
This also aids in maintenance. IP20 fin-
gerproofing is available through add-
on shields. This change affects NEMA
Sizes 1 and 2.
Load Lugs on Overload Relay Base
The load lugs have been moved from
the heater pack housing to the sensor
base of the 32A and 75A overload
relays. This permits wiring of the
starter prior to heater pack installation.
These overload relays are used on
NEMA Sizes 00 – 2 and 5 – 8.
New Auxiliary Contact Markings
CENELEC EN50012 — All auxiliary con-
tact blocks are identified by a two-digit
contact configuration code. Auxiliary
contact terminals are also identified by
a two-digit number in accordance with
International Standards approved by
CENELEC.
New Auxiliary Contact Ratings
All side and top auxiliary contact
blocks are now rated NEMA/UL P300
DC ratings and IEC 947 AC-15/DC-13
ratings.
New Class 10 and 20 Heater Packs
Because of improvements in the over-
load relays, the Class 10 and 20 inter-
changeable heater packs have been
modified. They can be used with the
new overload relays (Series B1) directly
or with the existing relays (Series A1)
when using an adapter lug kit.
Easy Magnet Coil Change
The 65 mm contactor and the connec-
tions on the 45 and 65 mm starters have
been modified to allow easy coil
changes at the distributor or in the field.

Certified Type 2 Coordination
Cutler-Hammer Freedom Series IEC
starters and NEMA starters are now
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 9000 Certification
When you turn to Cutler-Hammer
Products, you turn to quality. The
International Standards Organization
(ISO) has established a series of stan-
dards acknowledged by 91 industrial-
ized 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. This commit-
ment to quality will result in increased
product reliability and total customer
satisfaction.
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.
