Simet distribution block SIMBLOCK 81650002 — universal Al/Cu SUB 220, gray

Simet SIMBLOCK 81650002 is a universal distribution block designed for mixed aluminium and copper conductors with SUB 220 designation. The gray plastic housing and internal connection system allow secure termination of Al and Cu cables in distribution panels, junction boxes and switchgear. The product is intended for situations where reliable mechanical clamping, clear wiring arrangement and compatibility with both conductor types are required.

Advantages

The unit provides a single compact point for distributing electrical circuits while supporting both aluminium and copper conductors without the need for separate adapters. Its construction ensures stable mechanical clamping that reduces the risk of loosening over time. The gray colour helps visually distinguish this block within a panel, and the overall design facilitates quick installation and tidy routing of conductors.

Suitable for

• Residential and commercial distribution panels where Al and Cu conductors are used
• Junction boxes and connection chambers requiring mixed-metal terminations
• Retrofit projects converting or extending existing aluminium and copper cabling
• Industrial panels where compact, universal distribution points are needed

When it may not be suitable

This distribution block is intended for standard electrical distribution tasks and may not be suitable for specialized high-voltage, high-current switchgear beyond the stated SUB 220 application. It is not a replacement for devices that require integrated overcurrent protection, monitoring electronics, or enclosures rated for outdoor exposure without additional protection.

Key specifications

• Compatibility: designed for use with both aluminium and copper conductors
• Designation: SUB 220 type for standard distribution applications
• Housing colour: gray for easy visual identification
• Mechanical connection: secure clamping system suitable for mixed-metal terminations
• Application areas: distribution panels, junction boxes, residential, commercial and industrial installations

How to use

Prepare conductors by stripping insulation to the length recommended for the block’s clamping points. Insert the aluminium or copper conductors into the designated terminals and tighten the clamps to the specified torque or until a secure mechanical connection is achieved. Ensure conductors are clean and free of oxidation where possible; for aluminium conductors follow accepted practices for anti-oxidation treatment if required by local regulations. After installation, verify continuity and mechanical stability before restoring power.

What to consider before purchase

• Confirm conductor types and cross-sections are compatible with the distribution block
• Check that SUB 220 designation meets the voltage and application requirements of your installation
• Ensure the block’s physical dimensions and mounting style fit your enclosure or panel layout
• Review local electrical codes for any requirements regarding mixed Al/Cu connections and anti-oxidation measures

Usage recommendations

Use appropriate torque settings when tightening clamps, apply anti-oxidation treatment for aluminium conductors where required, and perform a post-installation inspection to confirm tightness and electrical continuity. Follow local wiring regulations and safety practices when working on live or de-energized circuits.
