- SPD included
- Dimensions: 160 × 240 × 112mm (W × H × D)

Installation notes
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.
FAQs
What does the 100A rating refer to?
It is the main-switch rating. The fuse, fuse holder, cable and circuit design determine the permitted protected load.
Which fuse links are included?
The supplied pack contains 63A, 80A and 100A links for selection to suit the installation.
Does it include an SPD?
Yes. Please contact Power & Data UK if you need the exact SPD model, classification or performance ratings for your design.
Is this the three-phase version?
For the version specifically listed with a four-pole main switch and three-pole fuse holder, see WFMS/3P. A pack of three fuse links does not establish three-phase suitability.
Can it be installed outdoors?
The enclosure is rated IP40. Select an enclosure and complete assembly suitable for the installation environment; this is not a weatherproof outdoor enclosure.
