Simet terminal block SCB 25 (81501003) Al/Cu feed-through branching connector, blue

Simet SCB 25 terminal block is an Al/Cu feed-through branching connector designed for reliable electrical distribution between aluminium and copper conductors. Supplied in blue, this connector allows a secure junction while preserving continuity in wiring systems. It is intended for use in panel assemblies, junction boxes and a variety of industrial or residential installations where mixed-metal connections are required.

Advantages

The Simet SCB 25 provides a solid mechanical and electrical connection between aluminium and copper conductors, reducing the risk of poor contact or galvanic corrosion when properly installed. Its feed-through branching design enables a continuous run of conductors while offering a branch point for additional circuits. The compact form factor and standardized terminal arrangement simplify installation in confined spaces and electrical panels. The blue insulating body gives visual identification of the connector type and intended application.

Suitable for

• Panel assemblies and distribution boards in residential and commercial buildings
• Junction boxes where aluminium and copper conductors meet
• Industrial wiring installations requiring branching points and continuity
• Retrofit projects that combine existing aluminium cabling with new copper runs

Key specifications

• Material compatibility: aluminium to copper conductor connection
• Function: feed-through branching connector for electrical conductors
• Color: blue insulating body for visual identification
• Form factor: compact terminal block suitable for panel mounting
• Application environment: suitable for residential, commercial and industrial electrical installations

How to use

Prepare conductor ends by stripping insulation to the required length and ensuring clean, oxide-free aluminium and copper surfaces where applicable. Insert conductors into the respective terminal points of the SCB 25 and secure them according to the manufacturer's torque or clamping instructions, making sure each conductor is firmly retained. When connecting dissimilar metals, follow accepted practices for anti-oxidation treatment or use compatible intermediate materials if specified by standards or site practice. Confirm continuity and correct polarity before restoring power.

Usage recommendations

Verify that conductor sizes and insulation types match the terminal block's rated capacity and observe local electrical codes. Use appropriate tools for stripping and tightening, and inspect connections periodically for signs of loosening or corrosion, especially where aluminium conductors are present.
