Product Overview
The One-Inlet Sixteen-Outlet Terminal Block is a high-density power distribution solution that splits one main incoming line into sixteen independent branch circuits. Designed for large metering cabinets and commercial distribution panels, it provides an organized, space-efficient method for managing numerous circuits while maintaining safety and ease of maintenance.
Internal Wiring Topology & Transparent Cover
The internal construction features a high-capacity copper busbar that runs the length of the block, with sixteen tap points for the outlet terminals. Key design elements include:
Phase & Neutral Marking
Each outlet position is numbered (1–16) and color-coded for phase identification (L1/L2/L3) in three-phase installations, preventing wiring errors during installation and maintenance.
01
Anti-Error Design
The terminal housing incorporates physical keying that prevents insertion of over-sized conductors and ensures proper conductor alignment before clamping.
02
Transparent Safety Cover
A clear polycarbonate cover provides IP20 touch protection while allowing visual inspection of all connections. The cover snaps into place without tools and can be sealed with a utility security wire.
03
Heat Dissipation
Spaced terminal positions and vented housing promote natural convection, preventing thermal buildup under full-load conditions.

Inlet & Outlet Wiring Specifications
| Connection | Cable Range (mm²) | AWG Equivalent | Screw Size | Torque |
| Main Inlet | 25–70 | 4–2/0 AWG | M8 | 8–12 N·m |
| Outlet 1–16 | 1.5–16 | 16–6 AWG | M4 | 1.5–2.5 N·m |
For three-phase balanced systems, distribute the 16 outlets as follows: 6 on L1, 5 on L2, 5 on L3 (or as close to equal as the load profile allows).
