Modular metal distribution board – 24 modules, 410x330x120 mm, IP54
Modular metal distribution board, designed for mounting modular electrical equipment in residential, commercial, technical, and industrial buildings. This is a 24-module surface-mounted steel enclosure with a locking mechanism, a metal lock with two keys, sealing gaskets, a mounting plate, and installation accessories. Due to its IP54 protection rating, the board can be used both indoors and in appropriately selected outdoor or technical environments.
Main idea:
This distribution board is designed for mounting and protecting 24 modules of electrical equipment, providing a robust surface-mounted metal enclosure with lockable doors, sealing gaskets, and an IP54 protection rating. It is a practical solution for installing circuit breakers, RCDs, RCBOs, relays, contactors, surge protectors, and other modular components.Number of modules

Steel / metalOperating principle
The modular distribution board serves as a protective and installation enclosure for electrical distribution, protection, and control equipment. Components such as circuit breakers, residual current devices (RCDs), combination RCBOs, surge arresters, relays, contactors, terminal blocks, and other modular electrical components can be mounted inside.
Surface mounting allows the board to be fixed directly to a wall or another suitable surface. The metal enclosure helps protect the internal equipment from mechanical impact, while the sealing gaskets and IP54 rating help reduce the ingress of dust and water splashes, provided the board is installed correctly.
What are the benefits of a 24-module metal board?
A 24-module board provides sufficient space for small to medium-sized electrical distribution nodes. It is suitable when you need to install multiple protection groups and organize lighting, socket circuits, equipment, heating, pumps, automation, or other electrical circuit protections in one tidy enclosure.Technical parameters
Product type Modular metal distribution board / enclosure Manufacturer IEK Model MKM11-N-24-54-Z EAN code 4606056087086 Number of modules 24 modules Dimensions 410x330x120 mm Protection rating IP54 Mounting type Surface-mounted Enclosure material Metal / steel Construction Modular metal board with door Locking mechanism Metal lock with two keys Sealing With sealing gaskets Included Mounting plate and installation accessories Purpose Installation of modular electrical equipment outdoors or indoors, according to environmental conditions Use location Residential, commercial, technical, utility, and industrial buildings Where is it used?
- In residential buildings – for mounting electrical groups, protection, and distribution equipment.
- In commercial premises – for small to medium-sized electrical distribution nodes.
- In technical rooms – for mounting automation, protection, and control components.
- In utility buildings and workshops – when a sturdier metal enclosure with a lock is required.
- In outdoor or semi-outdoor conditions – only after evaluating the environment, mounting location, cable entries, and IP54 limits.
Practical installation example
For example, the board is installed on a wall in a technical room or utility building. Inside, circuit breakers for separate lighting and socket groups, a residual current device (RCD), a surge arrester, terminal blocks, and other modular components can be installed.
Due to the lockable door, the equipment inside is better protected against unauthorized access, and the metal enclosure provides a stronger and more reliable mounting base for electrical apparatus.
Pros
- 24-module capacity – suitable for small to medium electrical nodes.
- Metal/steel enclosure – a more robust solution than standard plastic boxes.
- IP54 protection – better protection against dust and water splashes when installed correctly.
- Lockable door – metal lock with two keys helps restrict access to equipment.
- Includes sealing gaskets – helps maintain the enclosure's seal.
- Mounting plate and accessories – more convenient installation and equipment.
- Surface mounting – can be mounted directly on a wall or other surface.
Cons / limitations
- 24 modules may be insufficient – larger projects or complex systems may require a larger board.
- Metal enclosure requires grounding assessment – electrical safety regulations must be followed during installation.
- IP54 is not fully hermetic – the board is not intended for submersion or continuous direct water exposure.
- Requires proper cable entries – incorrect entries can reduce actual dust and moisture protection.
- Surface mounting is visible – not suitable if a fully flush-mounted solution is required.
Safety and installation notes
The modular distribution board is part of an electrical installation; before installation, it is necessary to assess the load, cable entries, protection devices, grounding, environmental conditions, and the specific electrical scheme.
- Installation must be performed by a qualified electrician in compliance with electrical safety regulations.
- The metal enclosure must be properly assessed for grounding according to the specific installation scheme.
- IP54 protection only applies if installed correctly – use appropriate cable entries and ensure the integrity of the sealing gaskets.
- The board is not intended for submersion in water or continuous direct water flows.
- Modular equipment must be selected based on load, network type, and protection requirements.
- For outdoor conditions, it is recommended to additionally assess protection against direct precipitation, UV exposure, condensation, and mechanical damage.
Quick selection guide
24-module metal distribution board – a suitable choice when you need a robust, surface-mounted, lockable, and IP54-rated enclosure for modular electrical equipment. It is suitable for electrical distribution systems in residential, technical, commercial, and utility buildings.

IP54Enclosure
Metal / steelSuitable when you need to:- mount up to 24 modules of electrical equipment;
- use a sturdier metal enclosure;
- have a lockable door with a metal lock;
- mount the board on a wall surface;
- protect equipment from dust and water splashes to the IP54 level.
Check before installation:- whether a 24-module capacity is sufficient for all planned equipment;
- whether a surface-mounted, rather than flush-mounted, board is needed;
- whether the 410x330x120 mm dimensions fit the installation site;
- whether the cable entries and sealing will maintain IP54 protection;
- whether metal enclosure grounding is provided according to the scheme.
Important reminder:
An IP54 board is not fully hermetic for submersion or continuous water exposure. In outdoor conditions, it is essential to correctly choose the mounting location, cable entries, and additional protection against precipitation and condensation.FAQ – Frequently asked questions
