42-circuit distribution box 110mm depth

A 42-circuit distribution box with 110mm depth is available in both flush-mounted metal and plastic designs, suitable for indoor electrical installations with IP40 protection.

Types and Materials

• Plastic Distribution Boxes: Typically IP40 rated, recess-mounted, and designed for 42 MCB modules. These boxes are lightweight, corrosion-resistant, and suitable for residential or commercial indoor use. They often feature a modular design for easy installation and maintenance, with a depth around 110mm for compact wall mounting .
• Metal Flush-Mounted Boxes: Constructed with a metallic frame and door, these boxes provide enhanced durability and fire resistance. They are designed for 42 modules and can be installed in hollow walls, offering a sleek, organized interior setup .

Key Specifications

• Module Capacity: 42 modules or circuits, compatible with standard miniature circuit breakers (MCBs) and some bolt-on or plug-on breakers depending on the model .
• Depth: Approximately 110mm, suitable for standard wall recesses or surface mounting depending on the model.
• Protection Rating: IP40 for indoor use, protecting against solid objects larger than 1mm but not water ingress .
• Mounting Options: Flush-mounted for a clean finish or surface-mounted depending on the installation environment .
• Standards Compliance: Many models comply with European low-voltage directives and safety standards, ensuring safe operation in residential and commercial settings .

Installation and Accessories

• Fixing Method: Metal boxes often use metal-claw fixing for secure installation in hollow walls .
• Circuit Breaker Compatibility: Accepts standard MCBs, with some models supporting up to 100A branch breakers and 200% rated neutrals for nonlinear loads .
• Optional Features: Some metal panelboards offer power monitoring, split bus interiors, and phenolic nameplates for organized labeling .

Practical Considerations

• Safety: Ensure the box is installed in a dry, indoor environment to maintain IP40 protection.
• Space Planning: Verify wall recess depth and width to accommodate the 110mm depth and 42-module layout.
• Future Expansion: Consider boxes with modular interiors or additional rows if future circuit expansion is anticipated. In summary, a 42-circuit distribution box with 110mm depth is available in both plastic and metal versions, flush-mounted or surface-mounted, with IP40 protection and compatibility with standard MCBs, making it suitable for organized and safe indoor electrical installations .
