Metals and Mining

Providing the industry's best protection for critical plant power systems

Industry - Metals and Mining

SEL equipment handles extreme operating environments with ease and ensures reliable power under the most demanding conditions. Our medium- and low-voltage protective relays easily retrofit into existing metal-clad switchgear and include our innovative arc-flash technology to protect personnel and equipment. Our industrial computing and communications products improve the reliability of human-machine interfaces (HMIs) with simple, intuitive software that empowers employees with real-time power system information.

SEL’s power management, process control, and automation products are designed for the extreme environmental conditions common in mining and metal-forming industries. SEL products monitor and protect expensive equipment, ensure an uninterrupted supply of electric power in every corner of your site or facility, and are backed by our ten-year, no-questions-asked warranty.

“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.”
