Operation and Protection of Motors up to 600Hp at 460Vac (800A)

Transcription

1 Operation and of Motors up to 600Hp at 460Vac (800) 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 UL508 approved and culus certified. This means your panels will fulfill the rigorous requirements of UL508 and will have the quality and performance as for all WEG products Standard or Custom y 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 and Full Voltage Non- Reversing Combination up to 250Hp at 460Vac. WEG s UL508 panel shops can manufacture any configuration of Non-Combination or Combination for any low voltage horsepower ratings. Some examples are listed below: Enclosed Contactors Full Voltage Reversing Reduced Voltage Magnetic (Part-Winding, Wye-Delta) Reduced Voltage Solid-State Multi-Speed Explosion Proof Whenever you need a reliable product to control & protect your application, WEG field specialists can help you find the best solution. Relays Enclosed Overloads Contactors Motor New Concepts Smaller size components allow selection of smaller enclosures which translates to cost savings. 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. wide range of industrial applications are covered: Pumps, Industrial Washing Machines, Compressors, lowers, Cutting Machines, Conveyors, Lumber Processing and many others.

5 Combination WEG s full voltage non-reversing combination starters represent a competitive alternative to the traditional NEM starters by offering: reduced overall dimensions, yet providing reasonable internal wiring space rotary through-the-door disconnect instead of the traditional flange operator UL/CS approved performance in more compact components. Two series are available off the shelf: MCC disconnect ESWC Series Motor protector ESWE & ESWF Series Combination Starter asics Combination starters are the most common type of packaged motor controllers. They are called combination because of their construction and combined functions required by the US National Electric Code (NEC): Motor, Motor ranch, Motor Controller and Motor Overload. UL & CS currently recognizes six different constructions of combination starters that meet the requirements of a motor branch circuit. Constructions Types through D are traditional starters that use either a listed disconnect switch and fuses or a listed circuit breaker as the disconnect means and for short circuit protection. Each type uses a separate UL508 listed motor controller and overload relay. Recently revisions on UL508 introduced the Type E and Type F starters.
