“I use SEL not just because of their industry-leading products and technical support,...but because SEL and its people are committed to doing the job right and making the user (me) happy with the end product.”
-Tim Burttram, Plant Electrical Engineer & Senior Project Manager at Cascade Steel Rolling Mills

“Reliability is a big issue due to the exposure a public utility has, and our local utility decided to swap out their other relays and go exclusively with the SEL-351 Relays. My recommendation (to choose SEL) wasn’t even challenged.”
-Charlie Adams, Senior Engineer at Marathon Oil

”SEL's field technical support has been very valuable to me. During our upgrade project, I got fast and reliable technical answers. And that’s simply how good SEL support is. I know we can count on SEL for that level of support every time.”
Don Elliott, Senior Engineer/Power Manger at Resolute Forest Products
