IP40 Surface-Mounted Distribution Box – Robust Enclosures for Professionals
IP40 surface-mounted distribution boxes (also known as consumer units or enclosures) provide reliable protection for electrical installations in dry indoor environments. With IP40 protection rating, they guard against solid objects >1 mm and are ideal for electrical contractors, construction companies, renovation firms, industrial facilities, research centers, and van conversions.
These high-quality surface-mounted enclosures are made from impact-resistant, self-extinguishing ABS plastic, comply with IEC 60670 standards, and enable fast, professional installation.
Benefits of IP40 Distribution Boxes for Business & Industry
- High mechanical strength – Impact-resistant housing suitable for construction sites and workshops
- Easy surface mounting – Pre-knocked cable entries on all sides, DIN rails, and PE/N terminals
- Scalable sizes – Available from 4 up to 72 modules, single to multi-row
- Wide temperature range – Typically -25 °C to +60 °C or higher
- Clear access & maintenance – Transparent or grey doors, often lockable
Applications of IP40 Surface-Mounted Distribution Boxes
IP40 enclosures are the go-to solution for dry indoor installations and are commonly used with NYM-J cables, H07V-K wires, and industrial cables:
- Commercial & Office Buildings: Sub-distribution for lighting, sockets, and machinery
- Construction & Renovation: Fast wall mounting in new builds and refurbishments
- Industrial & Manufacturing: Protection of controls and smaller production lines
- Research Centers & Laboratories: Clean and accessible power distribution
- Van & Vehicle Conversions: Compact onboard electrics for campers and service vans
- Electrical Contractors: Modular installation of MCBs, RCDs, and DIN rail devices

Frequently Asked Questions (FAQ) about IP40 Distribution Boxes
What does IP40 protection rating mean?
IP40 protects against contact with tools or fingers and solid objects larger than 1 mm. These boxes are designed for dry indoor use only (use IP54/IP65 for damp or outdoor areas).
What voltage and devices are these enclosures suitable for?
Up to 400 V AC. Perfect for MCBs (miniature circuit breakers), RCDs, and other DIN rail mounted devices in sub-distribution boards.
Can IP40 boxes be used outdoors?
No. For outdoor or damp locations, we recommend IP65-rated enclosures.
How many modules do I need for a typical commercial project?
It depends on the number of circuits. Small installations usually need 8–18 modules; larger projects often require 24–48+ modules.
Are the boxes lockable?
Many models are pre-drilled for locking cylinders – highly recommended for commercial and public installations.
Which cables are suitable for wiring these enclosures?
NYM-J, H07V-K, flexible industrial cables, or solar cables – depending on your application and required cross-section.
How do you mount a surface distribution box?
Directly to the wall with screws. Pre-knocked entries allow cable entry from top, bottom, and sides.
Do these products meet current standards?
Yes – fully compliant with IEC 60670, RoHS, glow-wire tested, and Class II.
Can the enclosures be expanded later?
Yes, most models support additional rows or extension covers.
