Read full descriptionThe WFMS/3P is the three-phase metal switch-fuse unit in the WFMS range. It combines a 125A four-pole main switch with a three-pole fuse holder in an IP40 enclosure.
Its enclosure measures 240 × 380 × 90mm (W × H × D), making it larger than the single-phase WFMS100 units. Check this size when planning mounting space and cable access.
- 125A four-pole main switch
- Three-pole cartridge fuse holder
- 22 × 58mm fuse format
- Polyester powder-coated metal enclosure
- 25mm and 32mm top and bottom knockouts
The 125A figure identifies the main switch. Confirm the fitted fuse-holder rating, permitted fuse links and supplied contents before ordering; the main-switch rating does not establish approval for 125A fuse links.

Images may show another configuration in the range. Select by the product code and listed contents.
What are the dimensions?
The enclosure is 240mm wide, 380mm high and 90mm deep.
Does the 125A main switch mean I can fit 125A fuses?
No. Main-switch and fuse-holder ratings must be checked separately. Confirm the permitted fuse-link rating for the actual supplied holder before selection.
Are fuse links included?
Please contact Power & Data UK to confirm the supplied contents and suitable links for your circuit. The three-pole holder description is not a promise of three included fuse links.
Is the WFMS/3P suitable for an outdoor wall?
It has an IP40 enclosure. The complete assembly must be selected for its environment; IP40 is not a weatherproof outdoor enclosure rating.

Installation and commissioning should be carried out by a qualified electrician using the instructions for the supplied assembly and fitted devices. Select fuse links for the circuit load, cable protection, holder rating and prospective fault current. Check terminal torque and enclosure earthing against the supplied instructions.
Use the designated isolation device before accessing the fuse holder. The fuse holder itself must not be used as a switch disconnector.
