Dimensions of double-door distribution boxes

Double-door distribution boxes typically range in width from 600mm to 1200mm, height from 400mm to 800mm, and depth from 100mm to 150mm, depending on the model and number of modules.Example DimensionsActi9 TPN DB (Schneider Electric): 604mm (W) x 422mm (H) x 101.4mm (D), 32 modules of 18mm, 8 ways, IP43 protection, double metal door .SPN Metalica Double Door DB (Havells): While exact dimensions are not listed in the manual, these boxes are designed for split neutral and multiple MCBs, typically similar in size to standard double-door boxes for residential and commercial use .HPL Double-Door Distribution Systems: Available in various sizes to accommodate domestic and commercial installations, generally following standard width and height ranges for double-door enclosures .Key ConsiderationsModule Capacity: Most double-door DBs are designed to hold multiple modular devices (MCBs, RCCBs, isolators) on DIN rails, with module counts ranging from 24 to 48 or more.Protection Ratings: Common IP ratings are IP43 or higher, with IK ratings (impact resistance) such as IK09 or IK10 for metal enclosures.Material and Finish: Metal or powder-coated steel is common, often with scratch-resistant finishes and magnetic or lockable doors.Compliance: Many boxes comply with IEC 61439-3, IS 8623-1, and IS 8623-3 standards for safety and performance .SummaryDouble-door distribution boxes are designed to provide easy access, enhanced safety, and flexibility for electrical installations. When selecting a box, consider the dimensions, module capacity, protection rating, and compliance standards to ensure it fits the installation space and meets electrical safety requirements. Typical dimensions for standard residential or commercial double-door DBs are 600–1200mm width, 400–800mm height, and 100–150mm depth.
