Description
What makes XL³ different from a standard Legrand DB?
The XL³ range is modular and rated for higher current than Legrand’s standard DX³ domestic/light-commercial DB range, making it the preferred specification for main and sub-main boards in industrial buildings, hospitals, and large commercial developments.
- XL³ 160/400 — for sub-main distribution boards in commercial buildings
- XL³ 800/4000 — for main distribution boards in industrial and large commercial installations
- Modular busbar and enclosure system, built to the specific current rating and way-count needed rather than a fixed off-the-shelf size
Does Fembosco assemble XL³ boards to a project spec?
Yes — XL³ is a component system, and Fembosco’s panel-building team assembles the enclosure, busbar, and breaker modules to match a project’s single-line diagram and current rating.
This is different from ordering a fixed-size domestic DB off the shelf: XL³ orders typically start with Fembosco’s engineers reviewing the project’s electrical design.
Frequently Asked Questions
Is XL³ suitable for a residential building?
XL³ is generally specified for commercial and industrial boards rather than individual apartments — for residential and light-commercial DBs, Legrand’s DX³ range (see our Legrand distribution board page) is the more common and cost-effective choice.
What information does Fembosco need to quote an XL³ board?
A single-line diagram, or at minimum the required current rating, phase configuration, and way-count, lets Fembosco’s engineers put together an accurate XL³ specification and quote.
