Frequently asked questions
What does a busbar board (متبورة) mean?
A busbar board has a built-in metal bar that carries power from the main breaker to every outgoing MCB, so you don't need individual jumper wires between breakers. It makes the panel tidier, safer and faster to install.
How many breakers fit in the ABB Primo EPRX-W312F?
It holds 36 single-pole MCBs (or 12 three-phase circuits) plus a 3P or 4P main incomer.
Does the board include circuit breakers?
No, it is supplied as an empty board. For a ready set, see the ABB Primo distribution board bundle with matched ABB MCBs at 4.5 kA or 6 kA.
Is it suitable for a single-phase home?
It is designed for three-phase (TPN) supplies with a 3P/4P incomer. For a single-phase meter, ask our team to confirm the correct incomer arrangement before ordering.
