| Where they come from | Siemens metal-clad switchgear at utilities, plants, and data centers. |
The type (GMSG or GMI) is on the nameplate along with rated kV, continuous amps, and interrupting rating.
- GMSG units from data center and plant upgrades carry strong numbers.
- Maintenance records and mechanism condition move the number.
- We do not publish prices. Metal, demand, and condition move them. You get a written number for your units.
Data centers replace medium voltage gear on schedules, not failures, so GMSG breakers out of those sites are often lightly used with full maintenance records. Send the records; they move the number.

Yes. Send photos of the gear and the access, and the removal plan comes with the offer.
Yes. Breakers usually sell better with the lineup they came from, and we can take the whole thing out.
We do. Medium voltage breakers are heavy and the mechanisms are not forgiving; our crew brings the lift truck and rigging. You de-energize and lock out.
