Gewiss GW40101 4 Module IP65 Surface Mount Enclosure
The Gewiss GW40101 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. Its IP65 rating makes it dust-tight and protected against water jets, and IK09 impact resistance suits exposed outdoor locations. The smooth-walled grey body is rated for 400V and 125A and is pre-arranged to take a terminal block.
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 143 x 210 x 100 mm (W x H x D) outer size.
- For more devices, step up to the 8-module GW40102 or 12-module GW40103. For sheltered indoor use, the IP55 GW40001 is a lower-cost option.
- Breakers and terminal blocks are not included and are bought separately.

FAQ
How many breakers fit in GW40101?
It takes 4 modules, for example four single-pole MCBs or two double-pole devices.
What is the difference between IP65 and IP55?
IP65 is fully dust-tight, while IP55 is dust-protected. Both resist water jets, so IP65 is the better choice for dusty or exposed outdoor sites.
Are breakers or a terminal block included?
No. The enclosure is pre-arranged for a terminal block, which is sold separately.
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.
