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. Compact Solution The small dimensions of CWB contactors lead to an overall reduction in the size of electrical panels compared to traditional contactor solutions with the same specification, with up to 40% more space than other products in certain current ranges. Auxiliary Contacts 1NO + 1NC Available on all items of CWB line, the 1NO + 1NC configuration covers the vast majority of applications. They have a self-cleaning feature, providing high reliability when switching low voltages and currents (17 V / 5 mA). For cases where more auxiliary contacts are required, there are common contact blocks (accessories) for the entire CWB range. Simple and Compact Mounting of Surge Surge Supressors Developed using plug-in technology, the surge suppressor blocks are housed in the contactors so that they take up no additional space. In order to prevent current or voltage surges in the control circuit, the suppressors are available in varistor, resistor-capacitor, diode and zener diode versions. CWB contactors with electronic control already have an internal surge suppressor included. Mechanical Interlocking Without Additional Space The CWB range has mechanical interlocks that are easy to install and do not add lateral space between the contactors. This feature ensures that the contactors are fixed side by side, resulting in better use of internal space in electrical panels.
