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
Made from cold-rolled steel with matte white polyester powder coating (RAL9003). Resists corrosion, scratches, and impact (IK05 rated).
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
Raised DIN rail creates extra vertical space for neat wire bending and termination. Ample room for RCBOs without crowding.
04
Secure Magnetic Lid Closure
Strong magnet holds the drop-down metal lid firmly shut. Prevents accidental opening while allowing quick access for maintenance.
05
Modular Wiring Configurations
Supports four main types:
• 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.
07
Clear Circuit Labeling Area
Integrated directory card behind the door for easy circuit identification and future troubleshooting.
08
Key Applications
Homeowners replacing old fuse boxes
Electricians installing new builds or renovations
Landlords upgrading rental property electrical systems
Contractors working on social housing or apartment complexes
Facilities managers maintaining commercial sub-panels

Fast FAQ – Answers for Pros & DIYers
Q: Are breakers included?
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).
Q: What's the difference between Dual RCD and High Integrity?
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.
Q: Is it compatible with UK-style DIN rails?
Yes - standard 35mm DIN rail. Fits all major European breaker brands.
Q: Do I need a diversity factor?
Yes - if loading MCBs continuously, apply 60% diversity factor per BS 7671 guidelines to avoid overheating.
