Compact steel distribution board for studio flats and small annexes. Conforms to BS EN 61439‑3, replacing old fuses with MCB/RCD protection. Pre‑punched knockouts allow flexible cable entry; raised DIN rail and pre‑fitted earth/neutral bars simplify wiring. Rated for incoming supplies up to 63A, ideal for lighting and socket circuits in minor refurbishments.

Key Features – Built for Electricians, Trusted by Installers
CE Certified to EU/UK Standards
Fully type-tested to BS EN 61439-3. Complies with Wiring Regulations BS 7671. Ready for inspection.
01
Heavy-Duty Steel Enclosure
Fabricated from cold-rolled steel with a matte white polyester powder coat (RAL9003). The compact 123 mm shell resists corrosion, surface scratches, and minor impact (IK05 rated), making it suitable for tight utility spaces.
02
Flexible Cable Entry
Pre-punched knockouts on top, bottom, left, right, and rear:
• Top/Bottom: 20mm, 25mm, 32mm
• Sides: 32mm + 40mm slots
• Rear: Large access slots for trunking or conduit
→ Route cables from any angle, even in tight spaces.
03
Spacious Interior Design
A raised DIN rail creates vertical clearance for neat wire bending behind four breaker positions. The shallow depth fits standard wall cavities and small cupboard installations without excessive projection.
04
Secure Magnetic Lid Closure
A strong magnet holds the drop-down metal lid firmly shut. Prevents accidental opening while allowing quick, tool-free access for breaker inspection or replacement.
05
Modular Wiring Configurations
Supports four primary arrangements:
• Main Switch CU: All circuits protected by individual MCBs + main isolator
• Dual RCD CU: Two RCDs split circuits into zones (cost-effective compliance)
• High Integrity CU: Mix of RCDs + RCBOs for maximum flexibility
• RCD-only CU: For sub-board applications (no main switch)
06
Pre-Installed Ground & Neutral Bars
Includes dedicated copper busbars for safe, code-compliant grounding and neutral connections. Termination points accept standard 2.5 mm² to 10 mm² conductors.
07
Clear Circuit Labeling Area
An integrated directory card is mounted behind the door for easy circuit identification. The card is replaceable, allowing updates when circuits are modified.
08
Key Applications
Small flat and studio fuse-box upgrades
Garden shed and garage electrical conversions
Kitchen and bathroom renovation sub-panels
Landlord rental property safety improvements
Electrician new-build cupboard installations

Fast FAQ – Answers for Pros & DIYers
Q1: Are breakers included?
A: No - consumer units are sold as enclosures only. Purchase compatible MCBs, RCDs, or RCBOs separately (e.g., Schneider, Hager, ABB, or Youtai's own range).
Q2: What's the difference between Dual RCD and High Integrity?
A: Dual RCD: Two RCDs protect groups of circuits. Cost-effective but less flexible.
High Integrity: Combines RCDs + RCBOs. Allows mixed protection per circuit. Ideal for complex layouts.
Q3: Is it compatible with UK-style DIN rails?
A: Yes - standard 35mm DIN rail. Fits all major European breaker brands.
Q4: Do I need a diversity factor?
A: Yes - if loading MCBs continuously, apply 60% diversity factor per BS 7671 guidelines to avoid overheating.
