Energy is powerful. Its presence allows us to dream and create new possibilities every day. At Legrand, we are committed to making the entire energy distribution process more efficient. To do this we follow, what we call, the ‘designeering process’, wherein we observe, understand, ideate, define, create a prototype, put it for user-testing, and see it through to final production. The result: you get products that give you the freedom to pursue all your projects and design your spaces with complete confidence, thus creating a culture of innovation and uniqueness that is synonymous with your style.

Air Circuit Breakers (ACBs), Miniature Circuit Breakers (MCBs), Distribution Boards, Busbars, MCCBs, Capacitors, Enclosures – they are everywhere. So, we put these important parts through our design approach, and what you see here are products that reflect this approach. They are developed to fit seamlessly within existing energy distribution set-ups, and comply with stringent quality certification standards. So be it the home, office, commercial establishment, industries, institutions – wherever they are used, they help to bring out the best result.
