Compact contactor brings ease-of-installation to the next level
WEG has launched the CWB80, a user-friendly, compact power contactor to help electrical engineers and installers save space in the cabinet while enhancing ease of installation. With width of 54mm and rated currents from 40 to 80A, the CWB80 is claimed to be more compact than conventional devices in the same power class, and is suitable for a range of industrial applications.
The CWB80 has been designed so that the power contacts are separated from the auxiliary contacts and control terminals to minimise the unit’s footprint. The mounting sockets for the auxiliary contacts save space and enable toolless mounting of two-pole or four-pole auxiliary contact blocks.
Thanks to a user-friendly modular design, installers can quickly and easily assemble high-performance combination starter modules with short-circuit and overload protection by mating CWB80 power contactors with WEG’s MPW80 motor protection circuit breakers. In situations where short-circuit protection is not required, thermal motor protection relays from the RW67 series can be attached directly.
For switched currents up to 38A, energy-efficient DC coils are said to enable direct control by a PLC without a supplementary coupling relay. The accessory auxiliary contact blocks and snubbers fit all contactors in the CWB series, simplifying stock-keeping, type selection and configuration.
