Indoor wall-mounted distribution box specifications

Indoor wall-mounted distribution boxes are designed for secure, organized, and accessible electrical or fiber-optic connections, featuring durable enclosures, cable entry knockouts, and optional locking mechanisms.

General Features

Indoor wall-mounted distribution boxes are typically designed for residential, commercial, or light industrial use. They provide a safe enclosure for electrical circuits or fiber-optic connections while allowing easy access for maintenance and inspection. Common features include:

• Enclosure Material: Durable plastic (polystyrene) or lightweight steel, often self-extinguishing, corrosion-resistant, and impact-resistant for long-term indoor use .
• Cover: Transparent or lockable covers for visual inspection without opening the box, sometimes with removable doors that can hinge left or right depending on installation needs .
• Mounting: Wall-mounted, either surface-mounted or flush-mounted, with pre-drilled holes or plastic corner pieces for secure attachment .
• Cable Entry: Knockouts or molded cable entry points at the top and bottom, often with integrated wire guides and fixing rings for organized cable management .
• Protection Rating: Typically IP20 for indoor use, providing protection against solid objects but not water ingress .

Electrical and Fiber-Optic Specifications

• Capacity: Varies by model; for fiber-optic boxes, up to 48 fibers with FC/SC/ST connectors or 96 fibers with LC connectors .
• Modules and Accessories: Compatible with LSA-PLUS® modules, jumper rings, overvoltage protection devices, and document wallets for labeling and organization .
• Earthing: Metal components and backplates require proper earthing according to standard electrical guidelines .
• Security: Some models include swivel handles and security locks to prevent unauthorized access .

Dimensions and Variants

• Sizes: Compact models for limited space or larger boxes for higher capacity installations. Depth and width vary depending on the number of modules or fibers supported .
• Customization: Doors can be removed during installation and re-hinged; overvoltage protection modules can be added above standard modules if needed .

Applications

• Electrical Distribution: Houses circuit breakers, switches, and wiring for residential or light commercial setups .
• Telecommunication and Fiber Networks: Termination, splicing, and interconnection of fiber-optic cables in indoor environments .
• Maintenance Efficiency: Transparent covers and organized internal layouts allow quick inspection and easier troubleshooting . Indoor wall-mounted distribution boxes combine robust protection, modularity, and accessibility, making them suitable for a wide range of indoor electrical and fiber-optic installations. Proper selection should consider capacity, material, IP rating, and compatibility with connectors or modules to meet specific installation requirements.
