Engineered to provide the most compact contactor solution, the WEG CWB range of devices offers a width space saving of up to 18%. Add to this that the range was developed according to IEC 60947 and UL 508 international standards and you will understand why this new generation contactor is finding such favour with electrical contractors.
Developed in two frame sizes, the new WEG CWB line of contactors meets a range of industrial and domestic applications requirements. The first contactor in the range, covering up to 38A, has a width of only 45 mm while the second contactor, ranging from 40 to 80A, has a width of 54 mm. Two mounting options, standard DIN rail or oblong mounting holes makes interchangeability easy.
Significantly, the space saving offered by the WEG CWB contactors, especially when compared to similar product ranges, will allow contractors to use six contactors where previously only five could be used.
Another innovative engineering feature is the use of WEG’s Zero-Width mechanical interlocking system. Traditionally contactors use a mechanical interlock device which is external to the contactor. The Zero-Width system facilitates quick and easy mechanical interlocking between contactors, without the need for tools. In addition, this feature allows the user to build a reversing starter up to 38A with a total width of only 90 mm.
Built-in front 1NO+1NC auxiliary contacts not only further enhance the space saving benefit of the WEG CWb contactors, but also eliminates the need for contractors to purchase additional auxiliary contacts. This feature also offers greater flexibility as it facilitates optimisation of the internal space in electrical panels.
In another innovation, the contactors have been engineered with integral surge suppressor blocks without increasing the physical size of the devices. This limits undesired interference which could be caused during the opening of the contactor coils and allows for the front mount surge suppressor to be easily removed without the use of special tools.
Energy saving is achieved through the low consumption of the coils used in the WEG CWB contactors and because the coil consumes such low current it is now possible to allow direct switching from PLCs without the need for interface relays. This facilitates both space and cost savings for the end-user.
Available at competitive pricing from Zest WEG Group’s branches and national distributor network, the WEG CWB range of contactors affords customers a high level of flexibility.
