DISTRIBUTION BOARDS
The distribution board (frequently referred to as the electrical panel or main switchboard) is undoubtedly the “heart” of any electrical infrastructure. It is from this central point that the energy supplied by the public grid is divided, managed, and protected before being distributed across the various circuits of a home, office, or industrial unit. A well-sized and structured board not only provides vital protection for equipment and people (against overloads, earth leakage, and short circuits) but also greatly facilitates any future maintenance work.
At JSL – Material Eléctrico, we design distribution boards that combine the robustness demanded by safety standards with the assembly ergonomics required by professionals. Our focus is on ensuring that the electrician has the space needed to carry out flawless wiring.
A Solution for Every Type of Application
To address the diversity of construction sites, our range of electrical panels is divided according to the installation method and the level of environmental exposure:
-
Flush-Mount (Recessed) Boards: The premium solution for new construction in the modern residential and commercial sectors. Designed to be concealed within walls (whether traditional masonry, brick, or plasterboard/drywall), these boards offer a discreet finish, with clean-design doors that blend with the architecture of the space.
-
Surface-Mount Boards: Perfect for renovations, annexes, garages, or buildings where chasing walls is not possible or desired. These boards are quick to mount and have been designed to pair perfectly with our technical trunking ranges, creating highly aesthetic and functional surface electrification routes.
-
Watertight Boards: When the installation moves outdoors, to industrial areas, laundries, wine cellars, or greenhouses, protection from the elements is non-negotiable. Our boards with high IP sealing ratings shield the modular switching devices (circuit breakers and RCDs) against severe dust ingress and water splashes.
Space, Modularity, and Safety
We believe that the interior of an electrical panel does not have to be a chaotic space. JSL distribution boards stand out for the generous distance between the DIN rail and the back of the enclosure, allowing ample room for routing and organizing electrical conductors behind the protection devices. We also provide generous knockouts for conduit entry and connections to earth and neutral busbars.
Manufactured from thermoplastic materials with high heat resistance (self-extinguishing and halogen-free), our boards ensure that in the event of a thermal anomaly, fire propagation does not occur.
