The WFMS100 is a metal switch-fuse unit with a 100A main switch for installations requiring a fused supply to downstream equipment. Its IP40 enclosure has a polyester powder coating and top and bottom cable-entry knockouts.

This is the base version with a 22 × 58mm fuse holder. For the version explicitly supplied with 63A, 80A and 100A fuse links, see WFMS100/3F.

  • 100A twin-pole main switch
  • 22 × 58mm cartridge fuse holder
  • Dimensions: 130 × 238 × 87mm (W × H × D)
  • IP40 metal enclosure
  • 25mm and 32mm knockouts on the top and bottom faces

The 100A figure is the main-switch rating. The permitted circuit load also depends on the selected fuse, fuse holder and installation design.
