Universal distribution block SUB 490 Al/Cu 82090 SIMBLOCK, grey 81652002

Universal distribution block for AC/DC installations

The SUB 490 distribution block is a solid and versatile solution for the safe distribution of electrical energy. Designed for both copper and aluminum wires, it is suitable for low-voltage installations with a voltage of up to 1000V AC or 1500V DC. The block's construction allows for flexible connection of wires with different cross-sections, making it an ideal element in electrical switchboards, power systems and photovoltaic installations.

Construction and application

The block is made of high-quality materials, which guarantees its durability and reliability. Its modular design facilitates mounting on TS 35 rails and allows for future expansion of the installation. The transparent housing allows for quick connection control without the need for disassembly. Thanks to the wide range of permissible wire cross-sections, this block finds application both in home and industrial installations.

Block mounting is simple and intuitive. It does not require specialized tools or extensive experience. This saves time and costs during installation. For installers, this means faster project completion, and for end-users – confidence in the proper functioning of the power system.

Key features:

• Versatility: Supports aluminum and copper wires in one block.
• Wide range of cross-sections: Possibility to connect wires with a cross-section from 1.5 mm² to 185 mm².
• Safety: Compliance with IEC 60947-7-1 standard ensures a high level of safety.
• Modularity: Easy mounting on TS 35 rail and possibility of installation expansion.
• Transparency: Transparent housing facilitates connection control.
• High current capacity: Rated current Cu up to 490A (depending on the cross-section of the input wire).

The SUB 490 distribution block allows connection of wires with the following parameters: rated voltage AC up to 1000 V, rated voltage DC up to 1500 V, rated current Cu up to 490 A. The wire input accepts wires with a cross-section of 95-185 mm², stranded wires with a ferrule 70-150 mm², and flat wires 24x10 mm². The wire outputs accommodate cross-sections from 1.5 mm² to 35 mm², stranded wires with a ferrule from 1.5 mm² to 25 mm².

The SUB 490 distribution block is a reliable solution for professionals and demanding users who value safety, functionality and ease of installation.
