Distribution box display h

The height (H) of distribution boxes varies by series, typically ranging from 75 mm to 140 mm for plastic enclosures.Standard Heights for Common SeriesHA, HK, LGD series: Heights range from 75 mm to 140 mm, depending on the model and number of ways (outlets) supported .MB-ABC series: Specific models have consistent heights:MB-ABC500: 95 mmMB-ABC700: 95 mmMB-ABC900: 95 mm Other series like MB-AF, MB-AS, MB-LF also follow similar height ranges, designed to accommodate modular circuit breakers and electrical components.Materials and FeaturesDistribution boxes are typically made from flame-resistant ABS plastic, polycarbonate (PC), or epoxy-coated/powder-coated stainless steel . These materials ensure insulation, impact resistance, and compliance with safety standards such as BS EN60439-3 and JB/T7121-93 . Some boxes include display windows or portholes for monitoring analog or digital instruments .ApplicationsThese boxes are used in residential, commercial, and industrial settings, including homes, high-rise buildings, hospitals, airports, and factories. Heights are designed to balance internal component space with compact installation requirements .Additional ConsiderationsModular design allows stacking or expansion without changing the overall height significantly.Smart DB boxes may include energy monitoring units or communication modules, which can slightly affect internal height requirements .Installation type (flush-mounted vs. surface-mounted) may influence the effective height visible on-site. In summary, when selecting a distribution box, the height (H) is a key factor for fitting the enclosure in the intended space while ensuring sufficient room for circuit breakers, fuses, and optional monitoring devices .
