600 Volts Maximum 50/60 Hertz
Application
GE’s magnetic motor starters listed here may be used for starting
full-voltage, nonreversing, single-speed ac motors up to 1600
horsepower, 600 Volts maximum, providing protection to the
motor against running or stalled overloads.
Their compact size and ease of wiring make them especially
suitable for motor control centers, custom-type control panels,
and switchgear equipment. Refer to page 1-7 for features of
basic starter.
Product Number Selection Instructions
1. Specify starter by complete Product Number.
Example: CR306C103 is a Size 1 starter with 230-240-Volt,
60-Hertz coil and in Type 1 general-purpose enclosure
2. The final letter of the Product Number denotes extra auxiliary
contacts (sometimes referred to as auxiliary interlocks). Order
the desired extra auxiliary contacts by replacing the final letter
with one from first column of auxiliary interlock table (see
page 1-134).
Example: CR306C103AAB is Size 1 starter with one extra normally open, auxiliary contact
3. Starter forms are available with coils of other ratings than
those shown on pages 1-9 to 1-10. Refer to coil suffix table,
page 1-8 for information. To order forms with other coil ratings,
insert suffix from coil table in place of fifth and sixth numbers
of listed starter Product Number shown on pages 1-9 to 1-10.
(Contact your nearest GE Representative for other
available starter coils not shown in table.) Example: A
CR306C102 NEMA Size 1, three-pole starter in Type 1 enclosure
with 24-Volt, 60-Hertz coil becomes a CR306C124 Product
Number.
4. For continuous rated motors with a service factor of 1.15 to
1.25 select the heater with maximum motor Amperes equal to
or immediately greater than the actual full-load current taken
directly from the nameplate of motor. Order heaters by complete Product Number from appropriate heater tables on pages
1-153 to 1-159
5. Order special modifications or forms not listed by complete
description using a listed Product Number as reference.
Example: Similar to CR306C104 except with 480/120-Volt
control transformer and red indicating light in cover.

6. Two-phase, four-wire forms are available. Contact nearest GE
Representative for pricing and ordering information.
7. Standard Coil Ratings
Standard Voltages (60 Hertz): 24, 115-120, 200-208, 230-240,
265-277, 460-480 and 575-600
Standard Voltages (50 Hertz): 110, 220, 380, 440 and 550
For price adders on special voltage and/or frequency coils,
refer to page 1-126.
8. 50-Hertz Starters
Pricing of starters for use on 50 Hertz at standard voltages is
the same as shown in table for 60 Hertz. Refer to page 1-4 for
three-phase horsepower ratings at 380 Volts, 50 Hertz.
