About SEL

Making Electric Power Safer, More Reliable, and More Economical

Our Mission

We work to make electric power safer, more reliable, and more economical.

Our Culture

Our culture of ownership ensures that our customers always come first.

Our Story

Innovation is at our core, from our very first relay to today’s solutions.

Our Leaders

Our leaders are driven by long-standing values and principles.

A Culture of Ownership

SEL is a 100 percent employee-owned company. Shared ownership is a key strategy for sustained growth, stability, and customer focus. Our employees are our shareholders, so there’s no short-term pressure to achieve quarterly results at the expense of what’s best for our customers or company in the long run.

At SEL, we take pride in doing what is right for our employees, customers, and communities all over the world.

We know our customers do not have to buy another one of our products. Therefore, it is our job to keep them coming back by providing the highest quality products and solutions, providing outstanding service, 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 Story

Our Leaders
