Power Distribution Block UL1953 AL Large 1000V 545A 3-pole 1 1000-250 in-1 1/2-13x1-3/8 out Box/Stud
Descrizione del prodotto
The Power Distribution Block (PDB) facilitates safe cable splicing and the distribution of primary power into secondary circuits, meeting UL508A and National Electrical Code® requirements. This model is part of the MPDB series and is designed for applications requiring up to 30 secondary outputs, with the option for single or dual conductor primary inputs.
Constructed with glass-filled polycarbonate, the insulators provide robust protection and can accommodate a maximum operating temperature of 80 °C. The block is equipped with optional adder poles that can be installed without tools, allowing flexibility in configuring primary and secondary wire combinations. Each pole features a test probe hole for circuit checking, enhancing safety measures.
The rated voltage is 1000V for both AC and DC applications, with a short circuit rating of up to 600 kA for certain classes. The connectors are available in tin-plated aluminum and are compatible with both solid and stranded copper wires. This product is ideal for feeder and branch circuit applications, ensuring compliance with required spacing of 1 inch through air and 2 inches over surface for uninsulated live parts of opposite polarity.

- 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.
