The Legrand Practibox S surface-mounted modular distribution board is a robust and reliable solution for managing electrical installations in residential and commercial environments. Designed to accommodate up to 36 modular devices across three rows of 12 modules each, this enclosure provides a structured and safe housing for circuit breakers, residual current devices, and other DIN-rail mounted components. The inclusion of a transparent door allows for quick visual inspection of the status of all installed devices without needing to open the unit, enhancing both convenience and safety.

Advantages

This distribution board stands out due to its high-quality construction and user-centric design, which simplifies the installation process for professionals. The surface-mounted configuration makes it ideal for locations where wall recessing is not possible or desired, offering a clean and professional appearance. The transparent door is crafted from durable materials that provide clear visibility while protecting the internal components from dust and accidental contact. With its generous capacity, it offers sufficient space for complex electrical setups, ensuring that all wiring remains organized and accessible for future maintenance or upgrades.

Suitable for

• Residential electrical distribution systems
• Commercial office spaces requiring modular device management
• Renovation projects where surface mounting is preferred
• Housing circuit breakers and RCDs in small to medium-sized installations

When it may not be suitable

This unit is designed for indoor use and is not suitable for outdoor environments where it may be exposed to direct moisture, rain, or extreme weather conditions. It is also not intended for industrial environments requiring high-impact protection or specific explosion-proof ratings.

Key specifications

• Capacity: 3 rows of 12 modules (36 modules total)
• Mounting type: Surface-mounted
• Door type: Transparent
• Material: High-quality durable plastic
• Compatibility: Standard DIN-rail mounted modular devices

How to use

The distribution board should be installed on a flat, stable wall surface using appropriate mounting hardware. Once the enclosure is securely fixed, the DIN rails allow for the easy snapping of modular devices into place. Wiring should be routed through the designated entry points to maintain order and safety. After all connections are verified by a qualified electrician, the transparent door can be closed to protect the components and provide a clean finish to the installation.

What to consider before purchase

• Ensure the wall space is sufficient for the dimensions of the 3x12 module unit
• Verify that the total number of modular devices does not exceed the 36-module capacity
• Confirm that the installation environment is dry and protected from the elements

Usage recommendations

Regularly inspect the distribution board for any signs of dust accumulation or loose connections to ensure long-term operational safety. Always ensure that the transparent door is kept closed to maintain the integrity of the internal components.
