NEW! WEG CWB Series Contactors

CWB Contactors - from 9 up to 80A

The CWB series contactors are developed according to IEC 60947 and UL 508 international standards, the new WEG CWB line of contactors meets the requirements of a wide range of industrial applications worldwide.
  • IEC current ratings from 9 Amp to 80 Amp
  • The CWB's compact dimensions allows it to take up less space inside electrical enclosures while still offering up to a powerful 18Kw @ 415V.
  • Dimensions of the 9A to 80A contactors are the same for both AC or DC coil voltages, making panel design and assembly easier.
  • DC models feature low consumption coils, allowing the CWC to be operated directly from a PLC without interface relays.
  • WEG RW67 overload relays are available in compact frame sizes from 0.28 A to 40A and are designed for use with, and as perfect complement to, the CWB contactors.
 cwbWEG CWB Series Contactors and RWB Overloads

Compact Solution

Because they are compact, 45 mm wide and available in up to 80 A (45 kW @ 400 V), CWB contactors lead to an overall reduction in size of electric panels if compared to traditional solutions of contactors with the same ratings.

      

Built-in Auxiliary Contacts 1NO + 1NC

The configuration of two built-in auxiliary contacts (1NO + 1NC) makes the application of CWB contactors more flexible in most automation systems, contributing to the optimization of internal space of electrical panels.

  
     

“Zero-Width” Mechanical Interlock

Mechanical interlock with no additional side space.

  
     

Simple and Compact Mounting of Surge Suppressor Blocks

Plug in concept:
Quick and easy toll-free mounting. A perfect fit without increasing the size.

  
     

Additional Contact Blocks

Side or front mounted auxiliary contact blocks with 4 additional auxiliary contacts.

  
     

DC Coils with no Inrush Pick-Up Current

Low consumption D.C. coils allow direct control through PLCs without the need for coupler relays.
