Application

Heavy Duty starters are designed for

across the line starting of single phase

and polyphase motors.

These controls are available in NEMA

Sizes 00 through 8. In addition to the

usual NEMA Starter Sizes, Siemens

offers three exclusive Half Sizes; 1

⁄

and 3

⁄

. These integral sizes offer

the same rugged, industrial

construction as our NEMA Sizes and

ensure efficient operating performance.

Half Sizes provide a real cost savings

by cutting down on over capacity when

NEMA Sizes exceed the motor rat-

ings. All Siemens Heavy Duty controls,

including our popular Half Sizes comply

with applicable NEMA and UL tests.

All starters are supplied with a NO

holding interlock that in conjunction

with an appropriate pilot device will

provide low voltage protection or

release.

NEMA starters are ideal for

applications requiring dependability

and durability. Typical applications

include use with machine tools, air

conditioning equipment, material

handling equipment, compressors,

hoists and various production and

industrial equipment as well as in

demanding automotive applications.

Starters are available as an open type

or in NEMA 1, 12/3/3R, 4 (painted), 4/4X

(stainless), 4X (fiberglass), and 7 & 9

enclosures.

Gravity Dropout

For added reliability, the gravity dropout

of the armature and contacts is assisted

by stainless steel springs which help

provide quick, precise opening of the

contacts.

45 Degree, Wedge Action Contacts

The 45 degree, wedge action contacts

reduce tracking and provide faster arc

quenching. The resulting self-cleaning

and reduced contact bounce mean

cooler operation and longer life for the

large silver cadmium oxide contacts.

Terminal Design

Control terminals are self-rising

pressure type.

Molded Coil

Magnetic coils are carefully wound and

then sealed in epoxy. Encapsulation

helps seal out moisture, promotes

heat transfer and resists electrical,

mechanical and thermal stresses.

Dual Voltage/Frequency Coil

Starters are available with dual voltage,

dual frequency coils. They are designed

to operate on either 50 or 60 Hertz.

Molded Stationary Contact Block

Thermoset materials resist arc tracking

and the stresses of heat and severe

impact.

Field Modification Kits

All starters can be modified in the field

with a complete range of accessories.

These include pushbuttons, selector

switches, pilot lights, auxiliary contacts

and surge suppressors.

Auxiliary Equipment

NEMA starters are available with

built-in START-STOP push buttons

for 3-wire control or a

HAND-OFF-AUTO selector

switch for 2-wire control

Field modifications such as auxiliary

contacts, pilot lights, push buttons,

selector switches, and fuse blocks

are available to meet particular

application requirements

Normally opened or normally closed

auxiliary power pole kits are available

for Sizes 00 through 1

⁄

Transformers can be ordered as

either factory or field modifications.

In some cases these may require a

larger enclosure

A full line of replacement parts are

available including contact kits, coils,

and overload relays

Size 5 & 6 Starters

PAGE 2
Heavy Duty Starters Features and Benefits Selection Half Size Starters Half-Size starters feature all the rugged performance characteristics of our NEMA rated starter sizes, but are fractionally sized to more closely match your exact motor rating. As a result, significant economic savings are made possible without sacrificing the reliability you expect from a heavy duty starter.
