Universal distribution block SUB 270 Al/Cu 82070 SIMBLOCK, grey 81655002

Universal distribution block for Al/Cu connections

This SIMBLOCK SUB 270 series distribution block is a reliable solution for safe and efficient connection of aluminum and copper wires. Designed for a wide range of applications – from building installations, through machines and automation, to renewable energy systems – it is a key element in any professional electrical installation. Its versatility stems from the ability to work in both alternating current (AC) and direct current (DC) circuits.

Design and application

The SUB 270 distribution block is characterized by a solid construction, ensuring stable connections even under high loads. It allows connection of wires with different cross-sections, both solid and stranded with ferrules. The ergonomic shape facilitates installation and ensures the installer's safety, minimizing the risk of contact with live parts. A transparent cover allows visual control of the connection status, and clear markings of input and output channels facilitate wire identification. The ability to connect blocks in sections provides flexibility in designing switchboards and adapting them to individual needs.

Advantages and benefits

• Versatility: Supporting both aluminum and copper wires in one block eliminates the need to use many different types of connectors.
• High permissible current value: Rated current up to 270A (when using Cu wires with a cross-section of 2 x 35 mm²) allows use in circuits with high power consumption. Possibility of working with wires with a cross-section up to 95mm².
• Safety: Solid construction and quality certificates ensure reliable and safe electrical connections.
• Easy installation: Ergonomic shape and clear markings facilitate the installer's work, reducing installation time.
• Flexibility: The ability to connect blocks in sections and adapt to different installation configurations increases system functionality.
• Wide range of wire cross-sections: Supporting wires with a cross-section from 1.5 mm² to 95 mm² (depending on the type) ensures compatibility with various installations.
• Durability: Made of high-quality materials guarantees long-term use even in harsh working conditions.
• Visual inspection: Transparent cover allows easy inspection of connections without disassembly.

The SIMBLOCK SUB 270 distribution block is an investment in safety, reliability and convenience for both professionals and end-users.
