For example, if the FLA rating is 75.2 amperes, heater packs
number H2022-3 should be selected from the above listed
Heater Pack Selection Table. For a 1.15 service factor motor
the FLA adjustment dial should be set at the location shown in
the above diagram by interpolating between the B position of
69.7 amperes and the C position of 77.1 amperes. If a 1.0
service factor motor would be involved, the dial should be
rotated counterclockwise one graduation (one half position) to
the dotted location in the diagram.
Power Poles — Power poles are available for the Sizes 00, 0,
1 and 2 contactors and starters only. The 00 & 0 power pole is
rated 12 amps (20 amp thermal) and the 1 & 2 is rated the same
as the basic devices.
A maximum of two power poles can be used per contactor or
starter. They cannot be field or factory installed. The power
poles have been designed to accept mechanical interlocks and
side mounted auxiliary contacts.
General Auxiliary Contacts Information — Auxiliary con-
tact blocks are designed for snap-on installation — fast, easy
installation (no tools required). Side mounted contact blocks are
available in 8 different circuit configurations — top mounted
contact blocks are offered in 21 different combinations. En-
closed type starters will accept side-mounted auxiliaries only
when mounted in standard enclosures. In larger enclosures, top
mounted contacts can be added.
All auxiliary contacts are of the bifurcated design with parallel
circuit paths. This redundant path provides very high reliability.
For rating information, refer to the “Auxiliary Contact Ratings”
table in this publication on Page 8.
Side Auxiliary Contacts — All starters are supplied as stand-
ard with one normally open (1 NO) auxiliary contact for use as
a holding circuit contact. Reversing starters have in addition,
one normally closed (1 NC) auxiliary contact for electrical inter-
locking purposes.
On Size 00, the holding contact occupies the 4th power pole
position (no additional space required). Up to two additional
contacts may be added to each side of a Size 00 starter. On
Sizes 0-2, the NO holding contact is located on the right side of
the contactor. Up to two additional contacts may be added to
the left side.
On Sizes 3-5, the NO holding contact is a base contact (on the
right on Size 3 and on the left on Sizes 4 & 5). Up to 2 additional
contacts can be mounted on the base interlock. On the opposite
side, up to 4 additional auxiliary contacts can be added.
On Sizes 6 & 7, there is 2NO/2NC contact block mounted on
the top-left position. An additional 2NO/2NC block may be
added to the top-right position. On Size 8, there is a NO/NC
block on the left back and a NO on the right back. Additional
NO/NC blocks may be added on the left and right front posi-
tions.
On Size 9, 2 auxiliary contacts are provided, each with 1 NO
and 1 NC.
Top Auxiliary Contacts — Open type starters, Sizes 00-2, will
accept top auxiliary contacts (up to four circuits possible). This
allows a total of up to 8 extra auxiliaries on Size 00 (6 extra
auxiliaries on Sizes 00-2).
Electronic Timer — The side mounted, five-function Elec-
tronic Timer attachment has a 1 NO - 1 NC relay output and is
designed for easy installation to any Freedom Series starter. It
is available in three different timing ranges from 0.3 to 300
seconds. Additional auxiliary contacts cannot be installed on
same side of starter when timer is used. For Sizes 3-5 a
separate mounting bracket is required.
• Timing Modes
– ON DELAY - Timing begins when timer is energized.
– OFF DELAY - Timing begins when timer is deener-
gized.
– ONE SHOT - A single pulsed output occurs when
timer is energized.
