Universal distribution block SUB 270 Al/Cu 82070 SIMBLOCK, blue 81655003

Universal distribution block for Al/Cu wires

The SUB 270 SIMBLOCK distribution block is a reliable solution for connecting aluminum and copper wires, designed for both professional installers and end-users. Its versatility stems from its ability to work in both alternating current (AC) and direct current (DC) circuits, making it an ideal choice for a variety of electrical applications. The block's design has been carefully considered for connection safety and durability, and its compact dimensions make it easy to install even in limited spaces.

Construction and application

The SUB 270 is distinguished by its solid construction and high-quality materials. Made from a combination of aluminum and brass, it provides optimal electrical conductivity and corrosion resistance. It is intended for splitting and branching electrical circuits in construction, control cabinets, switchboards, and renewable energy installations. Thanks to the wide range of permissible wire cross-sections, this block allows for flexible adaptation to specific installation needs. The unique core design and ribbing of the housing ensure effective heat dissipation, which translates into stable and long-lasting connections.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper wires in one block eliminates the need for additional transition connectors.
• Safety: UL 486E certification confirms compliance with high safety standards.
• Durability: Solid construction with high-quality materials guarantees long-term operation even in harsh conditions.
• Easy installation: The ergonomic shape of the block makes it easier for the installer to work, and clear markings of the input and output channels minimize the risk of errors.
• Wide range of wire cross-sections: Allows connection of wires with a cross-section from 1.5 mm² to 95 mm² (depending on the type of wire - solid or stranded with ferrule).
• High permissible current value: The rated current for Cu is 270 A at 2 x 35 mm² input, allowing use in circuits with high loads.
• Overheat protection: The special core design ensures effective heat dissipation, preventing overheating of connections.
• Sectioning capability: The block can be combined with other SIMBLOCK blocks into sections, increasing installation flexibility.
• Rated voltage AC/DC 1000V: A wide range of operating voltages allows for use in various electrical systems.
