Read full descriptionThe WFMSRT00-3F combines a time-delayed RCD and fuse holder in a metal enclosure, supplied with 63A, 80A and 100A fuse links. The enclosure is IP40 rated and measures 130 × 238 × 87mm (W × H × D).
A time-delayed RCD may be specified where coordination with downstream residual-current protection is required. Suitability depends on the actual RCD characteristics and the complete circuit design.
- Time-delayed RCD and cartridge fuse holder
- 63A, 80A and 100A fuse-link selection
- Polyester powder-coated metal enclosure
- 25mm and 32mm top and bottom knockouts
Before ordering, confirm the fitted RCD current rating, pole count, residual-current sensitivity and delay characteristics. The supplied fuse pack does not establish the number of fuse positions or three-phase suitability.

| Model | Main equipment | Fuse pack / selection | Dimensions W × H × D |
|---|---|---|---|
| WFMS100 | 100A twin-pole main switch; 22 × 58mm fuse holder | Base unit; ask about the required fuse link | 130 × 238 × 87mm |
| WFMS100/3F | 100A twin-pole main switch; 22 × 58mm fuse holder | 63A, 80A and 100A fuse links supplied | 130 × 238 × 87mm |
| WFMS100/3FSP | 100A main switch; fuse holder; SPD | 63A, 80A and 100A fuse links supplied | 160 × 240 × 112mm |
| WFMS/3P | 125A four-pole main switch; three-pole fuse holder | Three-phase version; confirm fuse links required | 240 × 380 × 90mm |
| WFMSRT00-3F | Time-delayed RCD; fuse holder | 63A, 80A and 100A fuse links supplied; confirm RCD specification | 130 × 238 × 87mm |
The three supplied fuse ratings are selection options, not a statement that three fuse positions are fitted. Match the chosen fuse to the holder, cable and circuit design.
Images may show another configuration in the range. Select by the product code and listed contents.
What is included?
A time-delayed RCD, fuse holder and three fuse links rated 63A, 80A and 100A. Confirm the exact fitted-device specification and wiring arrangement before ordering.
Is this a 125A four-pole RCD unit?
That RCD specification is not established for this listing. Confirm its current rating, pole count, sensitivity and delay before choosing it for an installation.
Does time delay guarantee selectivity?
No. The upstream and downstream device characteristics and installation design must be checked together to establish coordination.
Does the three-fuse pack mean three-phase protection?
No. Three supplied fuse ratings describe the contents of the pack, not the number of fitted fuse positions or the phase arrangement.

Before installation, obtain the wiring diagram and specifications for the supplied RCD and fuse holder. A qualified electrician should select the fuse link, verify enclosure earthing and complete the required inspection and testing. Keep protective-earth continuity independent of the switched conductors.
Confirm coordination with downstream protection using the actual RCD sensitivity and time/current characteristics. Do not assume a fixed delay, an adjustable setting or a particular pole count from the product name or image.
