Gewiss GW40001 4 Module IP55 Surface Mount Enclosure
The Gewiss GW40001 is a 4-module surface-mounted enclosure from the 40 CD range. It houses DIN-rail (EN 50022) modular devices such as MCBs, RCDs and isolators, and its IP55 rating protects against dust and water jets. The walls have knockout perforation centres for cable entry, and the enclosure is pre-arranged to take a terminal block. It suits small sub-circuits in villas, plant rooms and outdoor equipment areas.
Is this the right one for me?
- Choose it to house up to 4 single-module devices (a double-pole breaker uses 2 modules, a 4-pole device uses 4).
- Check that your wall space suits the 105 x 170 x 98 mm (W x H x D) outer size.
- For more devices, step up to the 8-module GW40003 or 12-module GW40005. For harsher outdoor exposure, consider the IP65 GW40101.
- Breakers and terminal blocks are not included and are bought separately.

FAQ
How many breakers fit in GW40001?
It takes 4 modules, for example four single-pole MCBs or two double-pole devices.
Are breakers or a terminal block included?
No. The enclosure is pre-arranged for a terminal block, which is sold separately. It comes with screwcaps, module masks, circuit labels and spare screws.
How do I make the cable entries?
Gewiss recommends its GW52401 milling cutter for the perforation centres.
Can I install it myself?
Fixing the box is simple, but wiring breakers into a fixed circuit should be done by a licensed electrician, especially for DEWA-notifiable work.
