DESCRIPTION
Non-Reversing Starters
Line voltage magnetic starters are used for starting polyphase
squirrel cage motors when full starting torque and the resulting
inrush current are acceptable. These starters also provide
protection to the motor against running or stalled overcurrents.
• Terminals — Size 00 through 1 ± screw type with
captive, backed-out self-lifting pressure plates. Fin-
ger proof covers, to reduce electrical shock, are
available. Size 2-9:
Control: Back-out saddle clamp with ± screws
Power: Box lugs, pressure type
• Mounting Position — Sizes 00-5: Horizontal or ver-
tical on upright panel. Sizes 6-8: 25° from vertical
maximum. Size 9: Vertical only.
• Connections — Straight through wiring — Line lugs
at top, load lugs at bottom.
• Standards —
UL listed (Size 00-8):
Open — File #E1491, Guide #NLDX
Enclosed — File #E19224, Guide #NLDX
UL listed (Size 9):
Open and Enclosed — File #E19224, Guide #NLDX
Except Size 9 Reverser Not UL Listed.
cUL listed (Size 00-8):
Enclosed — File #E19224, Guide #NLDX
CSA certified — (Size 00-8):
Open — File #LR353, Class #3211-04
Designed to meet or exceed NEMA standards.
• Ambient Temperature — –5°C to + 65°C
• Enclosures — Open or NEMA 1, 3R, 4X, and 12
enclosed. Snap-on cover control kits Size 00-4
NEMA 1; flange mount all other enclosure types.
• Construction — Designed specifically for use in
applications requiring NEMA ratings. Starters meet
or exceed NEMA standards ICS 2-1988.
• Mechanical/Electrical Life — Designed to 30 million
mechanical operations at maximum HP ratings for
Sizes 00 & 0, 10 million for Sizes 1& 2, 5 million for
Sizes 3-8. Designed to 3 million electrical operations
for Sizes 00-3 and 500 thousand for Sizes 4-8. Size
9 mechanical life in excess of 24K operations and
electrical life AC-3 (N/A); AC-4 in excess of 50 opera-
tions.
• Wiring — Wired for separate or common control.
• Holding Circuit Interlock — NEMA Starters Sizes 0-
3 are supplied with 1 NO auxiliary contact mounted
on the right hand side. On Size 00, interlock occu-
pies 4th power pole position — no increase in width.
Sizes 4 and 5 have NO interlock on left side, Sizes 6
and 7 have a 2NO/2NC auxiliary mounted on top
between arc-chutes and Size 8 has NO/NC auxiliary
on left side and a NO on the right. Size 9 supplied
with 2 auxiliary contacts. Each with 1 NO & 1 NC.
• Mounting — Supplied with steel mounting plate as
standard.
DESIGN CHARACTERISTICS (Continued)
• Auxiliary Contacts — Open type starters will accept
up to 8 NO or NC auxiliary contacts (4 for Size 8) —
includes holding circuit interlock. Enclosed contac-
tors and starters will accept up to 4 NO or NC auxil-
iary contacts up to Size 1 in NEMA 1 enclosures. For
larger sizes and other NEMA type enclosures, up to
8 NO or NC auxiliary contacts can be added.
• Mechanical Interlock & Reversing Kits — Avail-
able for field assembly of reversing contactors/start-
ers up to Size 7.
• Timer — Two types – Side mounted five function
Solid-State timer with timing ranges up to 5 minutes
for use with open or enclosed starters/contactors,
and top mounted pneumatic timers convertible from
OFF to ON delay with timing ranges up to 3 minutes
for use with open starters/contactors. Sizes 00-5
only.
• Transient Suppressor Kit — Limit high voltage tran-
sients produced in the control circuit when power is
removed from the coil. For Sizes 00 through 2 there
are three separate panel-mounted suppressors for
use on 120, 240 or 480 volt coils. For Sizes 3 through
5 there is one separate side mounted suppressor for
use on 120 volt coils.
• Control Circuit Fuse Block — Sizes 00-2 panel
mounted and Sizes 3-5 side mounted fuse holder for
control circuit protection. Uses Class CC rejection
type fuses, 30 ampere, 600 volt ac maximum.
• Locking Cover for Overload Relay — Snaps over
top of overload relays to prevent accidental turning
of trip or reset adjustments.
• Branch Circuit Fuse Block Kits — Sizes 00 through
2, 3-pole, top-mounted. Provide short circuit protec-
tion for branch circuits.
• Phase Monitor Relays — Designed to monitor
phase voltage unbalance, incorrect phase sequence
and line undervoltage of a 3 phase system. Sizes
00-5 only.
• Cover Controls for Enclosures — Numerous push-
buttons, selector switches and indicating lights are
available either factory installed or as kits to be
installed by others. These local control devices are
available for NEMA 1, 3R, 4X and 12 enclosures.
• Other Options for Enclosures — Many other op-
tional features such as meters, terminal strips, relays
timers, control power transformers, fuse blocks and
other accessories are available for installation in
enclosed contactors and starters.
