About ABB

Overview

ABB is a global technology leader in electrification and automation, helping industries improve productivity, efficiency, and sustainability through digital and energy technologies.

ABB was founded in 1988 and is based in Switzerland. Within the energy ecosystem, ABB is most relevant where metering, protection, switchgear, EV infrastructure, and automation need to work together as one system rather than as isolated components.

Product focus

  • Electrification products for low-voltage and medium-voltage power distribution
  • Automation and digital platforms for buildings, industry, and infrastructure
  • Monitoring, protection, and control equipment used in commercial and industrial energy projects

Typical applications

  • Smart buildings and campus energy management projects
  • Industrial power distribution and motor-control environments
  • Sites that need coordinated metering, protection, and automation
