UL1953 Power Distribution Block 1000V 545A 2-Pole 1 1000-250 in-2 350-#6 Box/Box
Descripción del producto
The Power Distribution Block (PDB) under the UL1953 standard serves as an essential component for efficiently managing electrical connections. This model features a maximum operating voltage of 1000V and an ampacity of 545A, making it suitable for heavy-duty applications. The design supports a dual conductor primary input and offers two secondary outputs, facilitating the distribution of power while ensuring safety and compliance with UL508A and the National Electrical Code®.
Constructed with tin-plated aluminum connectors, this block is compatible with both aluminum and copper wiring. The insulators are made from glass-filled polycarbonate, providing durability and resistance to breakage. Optional hinged safety covers enhance protection against accidental contact, allowing for circuit testing through designated probe holes.
Installation is straightforward with direct screw mounting, and the block can be customized with optional adder poles, enabling flexible configurations without the need for tools. Its flammability rating is classified at 94 V-0, ensuring safety in various environments. The MPDB series is designed for both industrial and commercial applications, where reliable power distribution is critical.

- 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.
- Max Operating Temp
- 80 °C
