Low-voltage power distribution box number

Low-voltage power distribution boxes are identified by specific model or article numbers, which vary by manufacturer and system type.Understanding Box NumbersA low-voltage power distribution box number typically refers to the manufacturer's catalog or article number that uniquely identifies a specific distribution board or switchgear unit. This number is used for ordering, installation, and reference in technical documentation. It often encodes information about the voltage rating, current capacity, modularity, and type of enclosure.Examples by ManufacturerSiemens: SIVACON S4 and ALPHA distribution boards use Article Numbers for identification. Each board's number corresponds to its configuration, rated current, and accessories. Siemens provides a conversion tool and online catalog to find the correct number for your application (Siemens LV 10, 2020) .ABB: The MNS® low-voltage distribution board and power cabinet are modular and multipurpose. Each unit has a specific product number conforming to GB7251.3-2006 standards, which identifies the type (distribution board, lighting control panel, metering panel, or power cabinet) and mounting style (wall or floor) .Fulleto Electric: The XL-21 low-voltage power distribution box is rated at 380V 800A and is identified by its model number XL-21, which specifies its voltage, current rating, and industrial suitability .LEONI Group: Intelligent power distribution boxes, such as iPDS and iPDM, are identified by their system-specific numbers, which indicate the voltage network (12V, 24V, 48V) and functional configuration for vehicle or industrial applications .Eaton: xComfort compact distribution boxes are identified by row and module numbers, such as 1–5 row KLV energy distribution boards, which indicate the number of modules and capacity for switching and protection devices .How to Find the Correct Box NumberDetermine the application: Industrial, commercial, residential, or vehicle-specific.Check voltage and current requirements: Low-voltage typically ranges from 230V to 400V AC, with current ratings from tens to thousands of amperes.Select the manufacturer and series: Each manufacturer has a catalog with article numbers.Use online tools or catalogs: Siemens, ABB, and Eaton provide online product selectors or conversion tools to match your requirements to the correct box number.Verify compliance: Ensure the box number corresponds to standards such as IEC/EN 60670-24, EN 62208, or GB7251.3-2006.SummaryThe low-voltage power distribution box number is a unique identifier assigned by the manufacturer to specify the exact type, configuration, and rating of the distribution box. It is essential for ordering, installation, and maintenance, and can be found in manufacturer catalogs, online tools, or technical datasheets. Always confirm the number against your voltage, current, and environmental requirements to ensure proper selection.
