## Long description

Legrand PRACTIBOX S is a modular surface-mounted distribution box designed for one row of up to 12 DIN-modular devices and equipped with a transparent door for visual inspection without opening. The enclosure accepts DIN-rail mounted protective devices and modular components, providing a compact solution for surface-mounted electrical distribution in residential and light commercial settings. The product is intended for installations where easy access and monitoring of circuit breakers and modular equipment is required.
Advantages
The enclosure offers a clear transparent door that allows quick visual verification of installed devices. Its modular 1x12 configuration supports flexible arrangement of circuit breakers and auxiliary modules along a single DIN rail.
