## Summary description

Simet SUB 400 distribution block (model 81651003) is a universal Al/Cu busbar connector designed for electrical panels and switchgear. Compatible with aluminium and copper conductors, it provides secure feed-through and distribution of power within control cabinets. The blue insulated housing identifies the circuit and facilitates organized wiring in industrial and residential installations.

## Long description

The Simet SUB 400 universal Al/Cu distribution block is a compact busbar connector intended for secure power distribution inside electrical panels and switchgear. Encased in a blue insulated housing, this model supports both aluminium and copper conductors and is designed to provide a reliable feed-through connection and organized wiring in industrial, commercial and residential installations.
Advantages
The SUB 400 offers a universal clamping solution for Al and Cu conductors and a clearly visible blue insulation that helps identify circuits in crowded panels. Its compact form factor saves space in distribution enclosures while maintaining accessible connection points for straightforward installation and maintenance. The connector is designed to ensure stable electrical contact and reduce installation errors when used with compatible conductors.
Suitable for (tasks / use cases)
Power distribution and feed-through connections inside control cabinets and switchgear
Industrial and commercial electrical panels requiring mixed aluminium and copper conductor connections
Residential distribution boards where a compact, color-coded busbar connector is needed
Applications that need clear circuit identification and tidy wiring organization
When it may not be suitable
This distribution block is intended specifically for connections between aluminium and copper conductors; it may not be suitable when specialty busbars, very high current ratings beyond the block's design, or specific certification requirements are present. For installations that require integrated fusing, surge protection, or additional accessories, a different component or supplementary devices may be needed.
Key specifications
Conductor compatibility: aluminium and copper
Application: feed-through and distribution inside electrical panels and switchgear
Housing: blue insulated body for circuit identification
Form factor: compact busbar connector suitable for dense panel layouts
How to use
Mount the distribution block in the panel at an appropriate location that provides mechanical support and access for wiring. Prepare conductor ends according to standard stripping and cleaning practices for aluminium and copper to ensure good contact. Insert conductors into the designated clamp points and tighten to the recommended torque values for the conductor type. After installation, verify mechanical retention and perform an electrical continuity and torque check as part of commissioning.
What to consider before purchase
Verify compatibility with the conductor cross-sections and types used in your installation
Ensure the block’s current rating and dielectric characteristics meet your system requirements
Confirm that the blue insulated housing and form factor fit into your panel layout and labeling scheme
Usage recommendations
Use proper torque settings and follow local electrical codes when connecting aluminium and copper conductors. Apply recommended anti-oxidation treatment where required for aluminium terminations, and include periodic inspections to ensure long-term reliability of the connection.
