Heavy Duty Starters 

General 

Features and Benefits 

^ 

All starters are supplied with a NO holding 

interlock that in conjunction with an 

appropriate pilot device will provide low 

voltage protection or release. 

Furnas® Brand 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, 3/3R, 4, 4X, 7 & 9, and 

12 enclosures. 

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 and pneumatic timers 

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. 

Standard Features 

Size 00-4 magnetic starters include the 

following standard features: 

• Rugged Industrial Design 

• Half Sizes for Cost and Space Savings 

« Dual Voltage, Dual Frequency Coils 

• Solid State or Ambient Compensated 

Bimetal Overload Protection 

• Front Removable Auxiliary Contacts 

• Wide Range of Accessories 

• Easy Coil Access 

• Overload Test Feature 

• Straight Thru Wiring 

• Gravity Dropout 

• Large Silver Cadmium Contacts 

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 four exclusive Half Sizes; 1%, 

2V2, 3 1 /2 and 4'/ 2 . 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 ratings. 

All Furnas 8 Brand Heavy Duty controls, 

including our popular Half Sizes comply 

with applicable NEMA and Ul_ tests. 

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 

• Furnas® Brand 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.

Max HP Plugging and Jogging 

Ratings shown are for applications 

requiring repeated interruptions of 

stalled motor current or repeated 

closing of high transient currents 

encountered in rapid motor reversal, 

involving more than five openings or 

closings per minute and more than ten 

in a ten minute period, such as plug 

stop, plug reverse or jogging duty. 

Ratings apply to single speed and multi 

speed controllers.

Control Ratings 

Continuous Amp Rating, Service Limit 

The service limit current represents the 

maximum RMS current, in amperes, 

which the controller may be expected 

to carry for protracted periods in normal 

service. At service limit current ratings, 

temperature rises may exceed those 

obtained by testing the controller at its 

continuous current rating. The trip current 

of overload relays or other motor 

protective devices shall not exceed 

the service limit current ratings of 

the controller. 

Ballast Type, Tungsten and Other 

Discharge Type Lighting Loads 

The characteristics of ballast type lamps 

are such that it is not necessary to 

derate Class 40 contactors below their 

normal continuous current rating. 

Class 40 contactors may also be used 

for controlling tungsten and other 

discharge type lighting loads, Class 40 

contactors are specifically designed for 

such loads and are applied at their full 

rating as listed in the Class 40 section. 

Resistance Heating Loads 

Ratings apply to Class 40 contactors 

which are employed to switch the load 

at the utilization voltage of the resistance 

heating or light producing 

element with a duty which requires 

continuous operation of not more than 

five openings per minute. 

Capacitor Switching KVA Rating 

When discharged, a capacitor has 

essentially zero impedance. For repetitive 

switching by a contactor, sufficient 

impedance should be connected in 

series to limit inrush current to not 

more than 6 times the contactor rated 

continuous current. In many installations, 

the impedance of connecting 

conductors may be sufficient for the 

purpose. When switching to connect 

additional banks, the banks already on 

the line may be charged and can 

supply additional available short circuit 

current which should be considered 

when selecting impedance to limit 

the current. 

The ratings shown for capacitor switching 

assume the following maximum 

available fault currents: 

Size 2-3: 5,000 Amp 

RMS Sym 

Size3 1 /2-5: 10,000 Amp 

RMS Sym 

Size 6: 18,000 Amp 

RMS Sym 

If available fault current is greater than 

these values, connect sufficient impedance 

in series as noted in the previous 

paragraph. 

The motor ratings in the table are 

NEMA standard ratings and apply only 

when the code letter of the motor is 

the same as or occurs earlier in the 

alphabet than is shown in the table 

below. 

Motors having code letters occurring 

later in the alphabet may require a 

larger controller.
