WEG ESW and ESWS series will now use the WEG CWB series of contactors

WEG Electric has announced that their ESW and ESWS series of starters will now use the WEG CWB  contactors. This also includes the non-metallic PESW/PESWS series.

The CWB contactors will replace the currently used CWM series of contactors. 

  • ESW/PESW series is for 3-phase applications up to 50 hp at 460V
  • ESWS/PESWS series is for single phase applications up to 10 hp at 230V

The enclosed starters come standard with START/STOP + RESET buttons or RESET button only. When different control options are needed, WEG also offers other control brackets as accessories that can be installed in the field.

Both of the new ESW and ESWS enclosed starters with CWB contactors 40 – 80A fits in the same M06 enclosure; 13in x 7.5in x 5.6in (H x W x D).

The ESV/ESWS series are non-combination enclosed starters and will now use CWB IEC contactors and associated thermal overload relays.
