Modular distribution board 36+6 modules flush-mounted, Eti-Polam ECG42 DIDO 001101027, white, metal door, IP40

The Eti-Polam modular distribution board 36+6 modules flush-mounted is a compact indoor electrical enclosure designed to install DIN-rail mounted protection devices and miniature circuit breakers for residential and light commercial systems. Supplied in white with a metal door and an IP40 rating, this unit provides a neat finished appearance when installed flush into a wall cavity and protects internal components from solid objects larger than 1 mm while remaining suitable for dry indoor environments.

Advantages

The distribution board offers a modular layout with 36 main module positions plus 6 additional auxiliary modules, enabling separation of circuits and flexible arrangement of protection and control devices. Its metal door improves mechanical robustness and provides a secure cover for the interior, while the flush-mounted design reduces protrusion from the wall for a clean installation. The IP40 rating and white finish make it suitable for typical indoor electrical rooms, corridors, and utility spaces where dust protection and aesthetic integration are required.

Suitable for

• Residential apartment and house breaker and RCD installations
• Small offices and light commercial electrical distribution
• Retrofit or new-build flush installations in internal walls
• Arrangements requiring organized DIN-rail mounting of multiple protective devices

When it may not be suitable

This distribution board is intended for indoor use and its IP40 rating does not provide protection against water ingress, so it is not suitable for outdoor installations or locations with high humidity or direct water exposure. It is also designed for DIN-rail devices and may not accommodate non-standard or oversized equipment intended for specialist switchgear.

Key specifications

• Module capacity: 36 main modules + 6 auxiliary modules
• Mounting type: flush-mounted (built-in)
• Door material: metal
• Color: white
• Protection rating: IP40 (indoor use)
• Intended equipment: DIN-rail mounted circuit breakers and protective devices

How to use

Install the enclosure into a prepared wall cavity, ensuring correct alignment and secure fixing to structural elements. Fit DIN-rail mounted devices into the available module positions according to the electrical design and maintain appropriate clearances for incoming and outgoing cables. Connect conductors to devices following local wiring regulations and label circuits for identification. Close the metal door after installation to maintain protection and appearance. Commissioning should be carried out by a qualified electrician who will verify earth continuity, insulation resistance and correct operation of protection devices.

What to consider before purchase

• Check the required number of module positions for your protective devices and any allowance for future expansion
• Confirm that IP40 is adequate for the installation location and that no moisture exposure is expected
• Ensure the metal door dimensions and mounting depth fit the available wall cavity and aesthetic requirements
• Verify compatibility with the DIN-rail equipment type and necessary clearances for cabling

Usage recommendations

Have a qualified electrician perform the installation and final testing. Plan the circuit layout in advance to make full use of the 36+6 modular configuration and leave space for labelling and future additions. Avoid installing in wet or unprotected outdoor areas due to the IP40 rating.
