About

Eco-Friendly

The CWB line uses only nontoxic and eco-friendly materials that are safe and sustainable.

Compact Solution

Because they are compact, 45 mm wide and available in up to 38 A, and 54 mm wide available from 40 to 80 A, 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.

Panel Assembly Flexibility

CWB contactors can be easily assembled on panels using 35 mm DIN rails or screws because their oblong holes are compatible with the old and traditional lines of contactors on the market.

“Zero-Width” Mechanical Interlock

For applications which require mechanical interlock between contactors, WEG has developed a new mechanical system that ensures compact and easy mounting without the need of any tools. WEG’s new mechanical interlock system allows the mechanical interlock between two contactors of the CWB line with “zero” additional side space and it is possible to assemble 90 mm wide reversing starters of up to 38 A.

Simple and Compact Mounting of Surge Suppressor Blocks

The coils of CWB contactors operate smoothly with a low level of disturbance in the control circuits. However, in order to reduce voltage surges due to the coil switching even further, WEG has developed surge suppressor blocks especially for the CWB line of contactors, which ensure limitation or even completely eliminate the undesired interferences that may be caused on opening the contactor coil. Surge suppressor blocks are easily mounted on CWB contactors without the need of any kind of tools and also without increasing volume.
