Switchgear & Protective Relays

Low- and medium-voltage switchgear parts, protective relays, and metering: current and long-obsolete.

Edmundson Industrial sources switchgear parts, protective relays, and metering across low- and medium-voltage equipment: drawout breakers, cells, relays, and instruments, current and long-obsolete. Send the equipment nameplate or the part number and we quote availability, condition, and lead time.

Independent sourcing, not an authorized distributor. We supply switchgear parts and relays new, surplus, and used-tested, with condition disclosed before sale. Manufacturer names are used here for reference only.

How do you specify switchgear parts?

  • Low-voltage or medium-voltage (and voltage class)
  • Breaker type and rating (drawout / fixed, amps, AIC)
  • Cell, cradle, or section details
  • Protective relay type (electromechanical or microprocessor)
  • Metering, CT / PT ratios, and instruments

How do we quote switchgear and relays?

  1. Send the equipment nameplate or the part number.
  2. We confirm low- or medium-voltage, the rating, and the relay or metering details.
  3. We quote condition, price, and lead time: new, surplus, or used-tested, timing confirmed with the request.
  4. Need a custom enclosure, panel, or mounting? Our fabrication side builds and modifies enclosures and panels to fit.
