Operation and Protection of Motors up to 600Hp at 460Vac (800A)
WEG enclosed starters series were designed to meet the requirements and flexibility frequently demanded
in industrial applications� Featuring components that
meet IEC design standards and UL horsepower ratings,
WEG enclosed starters are UL508A approved and
cULus certified� This means your panels will fulfill the
rigorous requirements of UL508A and will have the
quality and performance as for all WEG products
Standard or Custom
By having most of the processes in WEG facilities we
can manufacture not only the enclosed starters listed
on this catalog, but also any other custom panel your
application may require� Our Engineers will work
together with you to provide the perfect solution for
your application�
Perfect Solution
WEG offers options for both: Full Voltage Non-Reversing Non-Combination Starters and Full Voltage NonReversing Combination Starters up to 250Hp at 460Vac�

WEG’s UL508A panel shops can manufacture any configuration of Non-Combination or Combination Starters
for any low voltage horsepower ratings� Some examples are listed below:
• Enclosed Contactors
• Full Voltage Reversing Starters
• Reduced Voltage Magnetic Starters
(Part-Winding, Wye-Delta)
• Reduced Voltage Solid-State Starters
• Multi-Speed Starters
• Explosion Proof Starters
Whenever you need a reliable product to control & protect your application, WEG field specialists can help
you find the best solution�
New Concepts
Smaller size components allow selection of smaller enclosures which translates to cost savings� A wide
range of ratings and frames allow the components to be more closely matched to your application� Our
overload relays provide phase loss sensitivity, ambient temperature compensated for -4F to +140F (eliminating
the need for additional heaters), and automatic reset for remote applications�
A wide range of industrial applications are covered: Pumps, Industrial Washing Machines, Compressors,
Blowers, Cutting Machines, Conveyors, Lumber Processing and many others�
