Beyond the Blue Box
Lifetime support, supply chain security, training, and education—the benefits that back our products and solutions.
When you buy from SEL, you get our commitment to designing and manufacturing the highest quality products, the value of our ten-year warranty and lifetime support, and our dedication to empowering our customers with the educational tools they need to maximize their investment. It’s more than just a product—it’s SEL.
Service and Support
SEL backs our products and commitments with a ten-year warranty, no-charge diagnostic and repair services, local support, and a variety of test procedures and certifications.
It’s been this way at SEL for nearly 40 years and counting—a major reason why we’re North America’s most trusted provider of protective relays and ranked #1 in price, service, and support by international utilities.
All SEL products are guaranteed for ten years. We also provide free technical support as long as your SEL product remains in service.
From power management services and microgrid control to automation and cybersecurity, let our Engineering Services group partner with you to create a solution that meets your needs.
Quality in Manufacturing
We design and manufacture all our electronic devices in the U.S.A. This allows for direct collaboration and short feedback loops between our Research and Development and Manufacturing divisions, as well as increased supply chain security.
Cybersecurity Best Practices
We have a long history of solution and product design for operational technology (OT) environments. This has allowed us to build a deep understanding of the security considerations specific to OT networks, such as assumed trust between devices, deviation from baseline status, and how the concepts of confidentiality, integrity, and availability should relate to each other based on the application.
We build layers of defense and maintain the integrity of each layer’s purpose—in other words, we apply the right technology at the right layer. We believe simpler products are easier to defend and that the safety of the power system and availability of the protection and control devices come first.
Training and Education
A partnership with SEL doesn’t end at commissioning. We’re dedicated to continuous teaching and training opportunities, including education courses through SEL University, advanced documentation like technical papers and application notes, and webinars and conferences.
