Our Solutions

Custom Panels and Enclosures

SEL designs, manufactures, tests, and delivers custom protection, control, and metering panels as well as control cabinets and retrofit doors, all built to match your specifications and needs. Our panel factory technicians take pride in high-quality cable management practices, with wires clearly labeled and neatly routed to ease installation and future maintenance. Prewired solutions ease installation and minimize field wiring, while custom adapters and wiring conversion assemblies simplify integration of SEL equipment into your existing systems. Custom enclosure solutions are built to stringent SEL quality standards. SEL tests the final implementation of every manufactured system before shipping, reducing overall project costs and engineering time. This testing contributes to easier and faster commissioning. Our in-house panel factory simplifies assembly and shipping, and it enables seamless response to design changes on in-process projects.

All SEL equipment serial numbers, configurations, and accessories are nested under a parent serial number for full traceability. We can design and build single or multiple units, making projects economical at any scale. Single-part-number assemblies—including spares and uninstalled components—make orders, repeats, and approvals simple. 

We offer complete panel solutions, including:

  • Consulting, engineering design, and field services.
  • Panel and assembly manufacturing and testing in our in-house UL508A-certified panel shop.
  • Protection, automation, and control equipment manufacturing.
  • Easily extractable assemblies for all SEL-700 and SEL-2400 series products.
  • Standard cabinet design for indoor and outdoor applications, including stainless steel, mild steel, aluminum, fiberglass, and polycarbonate enclosures.
  • Enclosures, racks, bezels, plates, portables, swing panels, and doors.
  • Seismic- and UL-certified cabinets for distribution and automation in adverse environmental conditions.

Our Approach

Customization With One PO

SEL custom panels and enclosures integrate multiple pieces of equipment and hardware (from SEL and other vendors) into a single order, simplifying assembly and delivery. We work with you to understand your requirements and challenges so we can provide innovative, economical solutions. SEL creates a single part number for your custom enclosure solution design, streamlining repeat ordering and approvals.
