FuseBox 3 Phase

Find the Right FuseBox Three-Phase Board

The FuseBox three-phase range provides reliable power distribution for commercial, industrial and larger electrical installations. With robust metal construction, generous wiring space and a choice of configurations, these boards are designed to make installation and future maintenance straightforward.

⚡ Standard Three-Phase Boards – Available in 4, 8 and 12-way sizes with a 125A rating. These are ideal when surge protection is not required within the board or will be provided separately.

🛡️ Boards with Type 2 Surge Protection – Available in 3, 7 and 11-way configurations with an integrated Type 2 SPD. These help protect connected equipment against transient voltage surges and provide a convenient all-in-one solution.

🏢 Choosing the Right Size – Smaller boards suit workshops, retail units and individual distribution areas, while larger boards offer greater capacity for offices, commercial buildings and more complex installations. Allowing spare ways can also make future expansion easier.

🔧 Compatible Protection Devices – Complete your installation with FuseBox 10kA Type A RCBOs, single-pole MCBs and triple-pole MCBs, available in a selection of current ratings.

📦 Accessories – DIN rail blanks and 50mm tail glands are also available to help create a secure and professional installation.

Three-phase distribution equipment must be selected and installed by a suitably qualified electrician. Unsure which board, MCBs or RCBOs your project requires? Contact the Harbro team for friendly advice before ordering.
