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.

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.
