Its clean white finish and durable construction ensure that it integrates seamlessly into modern interiors while providing the necessary protection for your electrical infrastructure.

Advantages

This distribution board offers a high level of flexibility and ease of installation for various electrical setups. The spacious interior layout allows for efficient cable management and straightforward access to all installed modular devices. Constructed from high-quality materials, the enclosure provides robust protection against external factors, ensuring long-term durability and safety for the electrical components housed within. The aesthetic design is neutral and professional, making it suitable for visible installation areas.

Suitable for

• Residential electrical distribution systems
• Commercial office spaces
• Small-scale industrial workshops
• Retrofitting existing electrical panels
• Housing DIN-rail mounted modular devices

When it may not be suitable

This unit is designed specifically for surface-mounted installations and is not intended for flush-mounted applications where the board must be recessed into a wall. Additionally, it is not rated for outdoor use or environments with high levels of moisture or dust, as it lacks specific ingress protection ratings for such conditions.

Key specifications

• Capacity: 36 modules
• Configuration: 2 rows of 18 modules
• Mounting type: Surface-mounted
• Color: White
• Compatibility: Standard DIN-rail devices

How to use

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The board is mounted directly onto a flat wall surface using the provided mounting points. Once secured, the DIN rails allow for the simple snapping of circuit breakers and other modular components into place. Cables are routed through the designated entry points, and the front cover is attached to finalize the installation, ensuring all live parts are shielded.

What to consider before purchase

• Ensure the wall surface is flat and capable of supporting the weight of the board and installed components.
• Verify that the dimensions of the installation area match the physical footprint of the board.
• Confirm that the number of modules required for your specific circuit layout does not exceed the 36-module capacity.
• Check that all necessary modular devices are compatible with standard DIN-rail mounting.

Usage recommendations

Always ensure the main power supply is disconnected before performing any work inside the distribution board. Regularly inspect the connections to ensure they remain tight and free from signs of overheating or damage.
