## Long description

Legrand PRACTIBOX S modular flush-mounted distribution box configured for 4 rows of 18 modules each provides an organized enclosure for DIN-rail devices such as miniature circuit breakers and residual-current devices. The flush-mounted housing is designed for residential and small commercial electrical installations where a compact, recessed distribution solution is required. A transparent door allows visual inspection of installed devices without opening the enclosure, while internal mounting rails and knockouts support straightforward wiring and device arrangement.
Advantages
The PRACTIBOX S offers a compact flush-mounted design that saves wall space and provides a neat finish. Its transparent door enables quick visual checks of status indicators and fuse positions without exposing live parts. Modular rows and integrated DIN rails facilitate flexible arrangement and future expansion of protective devices. The enclosure is designed for organized cable entry and internal mounting, which reduces installation time and supports compliance with standard domestic wiring practices.
Suitable for
 Installation of DIN-rail circuit breakers and residual-current devices in homes

Always follow the latest national electrical codes and disconnect supply before working on the enclosure.
Usage recommendations

Verify the enclosure is installed in a location that allows access for maintenance and visual checks through the transparent door.
