Power Distribution Block UL1953 1000V 310A 2-pole 1 350-#6 in-4 #2-#14 out Box/Box
Descrizione del prodotto
The Power Distribution Block (PDB) offers a reliable solution for splicing cables and distributing primary power into secondary circuits. Compliant with UL508A and National Electrical Code® standards, this block is designed for fixed junction tap-off points, ensuring safety and ease of use.
With a maximum operating temperature of 80 °C and suitable for both aluminum and copper wire, the block supports a versatile range of applications. Its primary input can accommodate wire sizes from 350 to #6, while the secondary accommodates sizes from #2 to #14. The block's short circuit ratings vary, achieving up to 400 kA depending on the class, which enhances its safety profile in demanding environments.
Customizable configurations are facilitated by optional adder poles, allowing for tool-free stacking to create multi-pole units. Additionally, the virtually unbreakable glass-filled polycarbonate insulators and optional hinged safety covers provide enhanced protection and shock resistance. The block features direct screw mounting for installation, and its components include tin-plated connectors that ensure reliable connections for both solid and stranded wire types.
For effective installation, the block meets the required spacing of 1 inch through air and 2 inches over the surface between uninsulated live parts of opposite polarity. The MPDB series stands out with its construction and capability, making it suitable for various feeder and branch circuit applications.

- Adder Poles
- All sizes have optional adder poles for increased flexibility and ease-of-use. Adder poles can be stacked to form multi-pole units in the field without the use of tools. Adder poles allow for customization of primary and secondary wire combinations. End barriers are also available for sale, catalog numbers can be found in the catalog number selection tables for each size block.
- Wire Connectors
- Standard aluminum and copper wire connectors are available. Aluminum connectors accept both AL or CU wire while copper connectors accept CU wire only. Connectors are all 1-piece tin-plated. Many part numbers are rated to accept DLO-type fine-strand wire, allowing users to connect flexible conductors.
- Insulators
- Insulators are virtually unbreakable, made of glass-filled polycarbonate. “See-through,” hinged safety covers are optional and provide a greater degree of safety and shock resistance where required. Hinged covers can be installed without tools.
- Spacings
- 1 inch through air and 2 inches over surface between uninsulated live parts of opposite polarity meets requirements for feeder and branch circuit applications of UL508A.
- Safety Covers
- Polycarbonate safety covers provide dead-front protection. One cover is needed for each pole. Each cover has a test probe hole in the center for circuit checking. Covers are optional accessories and catalog numbers can be found in the catalog selection tables for each size block.
