Standard distribution box bracket dimensions diagram
Distribution box brackets typically feature adjustable mounting options with shelf lengths ranging from 300 mm to 1200 mm, supporting both end and center-mounted terminal blocks.
Bracket and Mounting Overview
Standard distribution box brackets are designed to accommodate terminal blocks, protector bars, and modular components. They often come as swivel-type mounting brackets that can be installed at the end or center of the frame, allowing flexibility in layout and component placement . Brackets are usually part of a welded assembly with bolt-on frame components, ensuring stability and ease of installation .
Typical Dimensions
- Shelf Length (Dimension B): Includes the length of the shelf plus any protector bars or terminal block swivel clips. Common lengths range from 300 mm to 1200 mm, depending on the number of ways or modules in the distribution box .
- Bracket Width: Designed to fit standard verticals in MDF (Main Distribution Frame) or IDF (Intermediate Distribution Frame) setups, typically adjustable to match frame spacing .
- Height: Brackets are compatible with verticals of varying heights, often specified per frame model. For example, standard frames may have heights from 600 mm to 2200 mm, with brackets positioned to align with horizontal shelves .
- Mounting Options: Brackets support end or center mounting, and can be used with adjustable guard rails, ground bars, and guide loops for cable management .
Additional Considerations
- Material: Brackets are usually made of steel or aluminum, sometimes with a powder-coated finish for durability.
- Compatibility: Ensure brackets match the distribution frame type (MDF or IDF) and the number of horizontal shelves.
- Adjustability: Many brackets allow fine-tuning of shelf position to accommodate different terminal block sizes or cable routing requirements .
- Industrial Standards: Brackets are designed to comply with electrical safety and mounting standards, ensuring secure installation and proper spacing for heat dissipation . By selecting brackets with these standard dimensions and features, installers can ensure flexible, safe, and code-compliant distribution box setups for both commercial and industrial applications.
