  • Voltage Ranges listed in table are -20% to +15% of nominal. For 3D-240 models, this is -20% of 208 Vac (166 Vac) to +15% of 240 Vac (276 Vac). Operating Frequencies: 50/60 Hz
  • Delta models, WNC-3D-240-MB, WNC-3D-400-MB, and WNC-3D-480-MB, work either with or without a neutral connection, but require a line-to-line voltage connection for operating power.
  • Add 10% to the indicated price for any option or valid combination of options. For a list of available options see the Modbus Options page.
