Dimensions of a three-circuit distribution box

Fiber and communications infrastructure knowledge brief Published 27 Jul 2023

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

A typical three-circuit distribution box has dimensions around 298 mm in width, with depth and height varying by model, designed for wall or pole mounting with DIN rail compatibility.

Standard Dimensions

Width: Approximately 298 mm depending on the specific variant and manufacturer. Height and Depth: Vary by model; for example, some compact boxes have a depth of 120 mm and adjustable DIN rail depth of 15 mm. Cable Entry: Rear cable entrance typically around 400 x 35 mm, often fitted with a cable brush for protection.

Material: Commonly made from ASA (Acrylic Styrene Acrylonitrile) or steel plate (1. 5 mm), with finishes like RAL 7035 for corrosion resistance. Mounting: Can be wall-mounted or pole-mounted, with provisions for 19" rack profiles or adjustable studs for easy installation.

Technical FeaturesDIN Rail Compatibility: Supports modular MCBs, RCCBs, or switches, with adjustable depth for alignment. Earthing: Equipped with earthing rails (e.g., 10 x 8 mm) for safety. Protection Ratings: IP44 with cover in place, IP2X with cover removed, ensuring protection against dust and accidental contact.

Terminal Blocks: Electro tin-plated brass with polycarbonate shields for phase and neutral terminals.

Considerations for Selection

Ensure the box accommodates the number of circuits and devices required. Check local wiring regulations for minimum box volume and safety compliance. Consider future expansion; some boxes allow additional modules or extension boxes.

Verify mounting options and cable entry points to match installation site requirements. These specifications provide a reliable reference for selecting or installing a three-circuit distribution box in residential, commercial, or light industrial applications.
