Making Electric Power Safer, More Reliable, and More Economical
SEL specializes in creating digital products and systems that protect, control, and automate power systems around the world. This technology prevents blackouts and improves power system reliability and safety at a reduced cost. A 100 percent employee-owned company headquartered in Pullman, Washington, SEL has manufactured products in the United States since 1984 and serves customers worldwide.
As part of our commitment to designing and manufacturing reliable, high-quality products, we research, design, build, test, distribute, teach, and support each of our technologies at SEL facilities. Assembled SEL products travel directly from our hands to where they need to be, so we feel confident that you and your customers can rely on them to keep critical systems fully operational.
Put simply, we keep the lights on.
Our Mission
Every day, we work to make electric power safer, more reliable, and more economical. This is something all of our employee owners take to heart because when electric power is safe, reliable, and economical, it changes people’s lives. From generation to consumption, our products and solutions are critical at every stage of the electric power system. They prevent blackouts and restore power faster; add cybersecurity, automation, and communications; and incorporate new, cutting-edge technologies that we invent, design, and manufacture right here at SEL.

As a 100 percent employee-owned company, we take pride in doing what is right for our employees, customers, power systems, and communities all over the world.
We know that none of our customers have a responsibility to ever buy another one of our products. Therefore, it is our job to keep them coming back by providing the highest quality products, forming genuine partnerships, and never stopping at “good enough.” Part of this driving force comes from the values that define our company and the principles we live by every day.

Our History
Innovation is the heart of SEL. Inspired by his research as a doctoral candidate, Dr. Schweitzer invented the first microprocessor-based digital protective relay, the SEL-21, which revolutionized the electric power industry and provided new functionality in power system protection. He made his first sale to Otter Tail Power Company in 1984.
The grit, passion, and creativity that drove SEL from a basement with a handful of employees to a worldwide company with over 5,000 employees continue to be a driving force and source of inspiration today.
SEL devices are manufactured in our four U.S. manufacturing centers, and our products are integrated into panels in regional assembly factories. We also have offices around the world so we can stay close to our customers.
