## Summary description

Simet SIMBLOCK SUB 400 (81651002) is a universal Al/Cu distribution block designed for safe electrical connection and distribution between aluminium and copper conductors. Supplied in grey, it supports bi-metallic termination to prevent galvanic corrosion when joining dissimilar metals. Suitable for electrical panels, service junctions and industrial or residential wiring installations.

## Long description

Simet SIMBLOCK SUB 400 is a universal Al/Cu distribution block designed to provide a safe and reliable electrical connection between aluminium and copper conductors. Housed in a grey insulating body, the block supports bi-metallic termination methods to reduce the risk of galvanic corrosion when joining dissimilar metals and is intended for use in distribution boards, service junctions and general wiring installations in industrial and residential environments.
Advantages
The SIMBLOCK SUB 400 offers a compact and robust solution for combining aluminium and copper conductors in one terminal point, with construction materials chosen to minimise contact corrosion and ensure stable conductivity. Its universal design simplifies installation across different conductor types, and the grey insulated enclosure provides mechanical protection and basic electrical insulation for internal connections.
Suitable for
 Distribution panels and consumer units where Al and Cu conductors meet
 Service junctions and repair points on electrical feeders
 Industrial and residential wiring systems requiring a bi-metallic termination
 Retrofitting or upgrading existing installations with mixed-metal conductors
When it may not be suitable
This distribution block is intended specifically for combining aluminium and copper conductors; it may not be suitable where only specialised high-current busbar systems, bespoke terminal blocks with integrated fusing, or where IP-rated external enclosure protection is required. For applications exposed to corrosive environments, high mechanical stress, or outdoor installation without additional protection, an enclosure or a product with a higher environmental rating should be considered.
Key specifications
 Universal Al/Cu compatibility for bi-metallic termination
 Insulated grey housing for mechanical protection and basic electrical insulation
 Compact form factor suitable for panel mounting
 Designed for use in distribution boards, junctions and general wiring
How to use
Mount the SIMBLOCK SUB 400 in the distribution panel or junction box according to available mounting points and align conductor entry so that aluminium and copper conductors are placed in their respective clamping zones. Strip conductor insulation to the recommended length, insert conductors fully and tighten terminal screws to the torque value recommended for the conductor type and cross-section. Verify tightness and electrical continuity after installation and, if necessary, apply appropriate corrosion-inhibiting compounds at the bi-metallic joint following local regulations and best practices.
What to consider before purchase
 Confirm compatibility with conductor cross-sections and the intended installation layout
 Check mounting space and panel arrangement to ensure proper fit
 Assess environmental conditions (indoor vs outdoor, presence of corrosive agents)
 Ensure required torque values and installation tools are available for secure termination
Usage recommendations
Use appropriate torque settings and, where applicable, anti-oxidant compounds for aluminium conductors. Perform post-installation checks for mechanical tightness and electrical continuity. For installations in demanding environments, combine the block with a protective enclosure or choose a product with a suitable environmental protection rating.
