Mega - Midi Distro Box 1-4
📝 Mega/MIDI Distribution Block – 1 × Mega Fuse + 4 × MIDI Fuses
This Mega/MIDI distribution block provides robust, centralised protection for high-current 12–24V DC systems. With one Mega fuse input/output and four MIDI fused circuits fed from a solid internal busbar, it delivers professional-grade load distribution for campervans, caravans, RVs, 4WDs, marine and industrial applications.
⭐ Essential Benefits
• Mega fuse main protection – Safeguards the primary power feed against high-current faults.
• Four MIDI-fused circuits – Individually protects downstream accessories and subsystems.
• Integrated busbar – Ensures stable, efficient power delivery across all circuits.
• Dust-resistant, heavy-duty housing – Built for harsh off-road and marine environments.
• Versatile application range – Ideal for caravans, 4x4s, dual battery systems, mining, marine and industrial power setups.
⚙️ Functionality
A single high-current cable feeds the Mega fuse, which protects the main distribution line. From there, an internal copper busbar supplies four MIDI fuse channels, each independently fusible. This allows safe power delivery to demanding loads such as inverters, DC-DC chargers, winches, compressors and auxiliary power modules while keeping the primary circuit protected.
