Specifications and dimensions of embedded distribution box

Embedded distribution boxes come in various sizes and types, typically made of flame-resistant ABS plastic, with dimensions ranging from 100–415 mm in length, 75–140 mm in height, and 105–323 mm in width, supporting multiple ways (outlets) for modular electrical installations.

General Features

Embedded distribution boxes are designed for modular electrical installations in residential, commercial, and industrial settings. They are commonly used for AC circuits at 50 Hz, with rated voltages of 220V/380V. Most boxes are made of flame-resistant ABS plastic, offering impulse resistance, excellent insulation, and flame-proof properties. They comply with standards such as BS EN60439-3 and JB/T7121-93, ensuring safety and reliability during operation .

Dimensions and Series

Different series of embedded distribution boxes have varying dimensions and capacities:

• HA, HK, LGD Series: Length 100–415 mm, Width 105–323 mm, Height 75–140 mm .
• MB-ABC Series:
  • MB-ABC500: 200 mm (L) × 174 mm (W) × 95 mm (H)
  • MB-ABC700: 255 mm (L) × 172 mm (W) × 95 mm (H)
  • MB-ABC900: 328 mm (L) × 172 mm (W) × 95 mm (H)
• MB-AF, MB-AS, MB-LF Series: Similar modular designs with varying lengths, widths, and heights to accommodate different numbers of ways .
• TOP Series (TOP-TS, TOP-TF, TOP-LS, TOP-PS, TOP-PF, TOP-S): These boxes range from 1-way to 36-ways, with dimensions specified for length, width, and height according to the number of ways .

Installation and Mounting

Embedded distribution boxes are designed for flush mounting within walls or panels. They feature modular structures that allow easy installation and dismounting. The boxes often include predefined mounting sizes and modular slots for circuit breakers or other electrical components .

Additional Features

• Airflow and Ventilation: Some specialized distribution boxes, like the Air Excellent DB816, are designed for air distribution in ventilation systems, with multiple duct connections, internal air restrictor rings, and flexible placement options on ceilings or walls .
• Cable Management: Standard cable lengths for embedded boxes are available in 1 m, 2 m, 3 m, 5 m, or 10 m, depending on the installation requirements .
• Safety and Compliance: Boxes are tested for flame resistance, impulse proofing, and insulation, ensuring compliance with electrical safety standards .

Summary

Embedded distribution boxes are versatile enclosures for electrical circuits, available in various sizes, series, and configurations. They are primarily made of ABS plastic, support multiple ways for modular components, and comply with international safety standards. Selection depends on the number of ways required, installation type, and specific application, whether for residential, commercial, or industrial use .
