## Summary description

Legrand PRACTIBOX S 4x18 is a surface-mounted modular distribution enclosure designed to house up to four rows of 18 modules. The unit features a transparent door for quick visual inspection of circuit breakers and DIN-rail mounted devices, a compact design for wall mounting, and is intended for residential or light commercial electrical distribution and protection installations.

## Long description

Legrand PRACTIBOX S 4x18 surface-mounted distribution enclosure with transparent door is designed to accommodate up to four rows of 18 DIN-modules for residential and light commercial electrical distribution. The compact wall-mount box provides visible access to circuit breakers and DIN-rail devices through a clear front door, simplifying quick inspections without opening the panel. Its surface-mounted format allows installation where flush mounting is impractical, and the enclosure is made to integrate with standard modular protection components and wiring practices.
Advantages
The transparent door enables visual verification of module status without removing the cover, saving time during routine checks. A surface-mounted format reduces wall preparation and is suitable for retrofit or new installations where wall cavities are limited. The enclosure supports standard DIN-rail modular components, offering compatibility with a wide range of breakers, residual-current devices and terminal blocks. The compact footprint and clearly visible internal layout improve accessibility for maintenance and future expansion.
Suitable for
Residential electrical distribution and protection panels
Small commercial or office power distribution
Retrofit projects where flush mounting is not feasible
Temporary installations or utility rooms requiring visible breaker status
Key specifications
Capacity: up to 4 rows of 18 DIN-modules

Front: transparent hinged door for visual inspection
Compatibility: accepts standard DIN-rail mounted protective devices and modular accessories

How to use
Mount the enclosure on a suitable vertical surface using appropriate fixings and ensuring the box is level. Install DIN-rail and mount modular protective devices following electrical regulations and manufacturer instructions for each device. Route incoming and outgoing conductors through the provided knockouts or cable entry points, secure wiring inside using terminal blocks or wiring ducts, and close the transparent door to permit visual checks. Always isolate supply and verify circuits are de-energised before working inside the enclosure.
Usage recommendations
Install and commission the enclosure as part of an electrical installation only by a qualified electrician. Ensure compatibility of breakers and protective devices with the enclosure’s capacity and local electrical standards. Keep the transparent door clean to maintain clear visibility of device positions and labelling.
