Find the family.
Then the exact fit.

72.5–1,200 kV; roughly 2,000–8,000 A; 31.5–80 kA depending voltage family

52–1,200 kV; bay ratings generally 1,250–8,000 A and 31.5–80 kA

72.5–420 kV typical published hybrid range; 31.5–63 kA; compact outdoor bays

1–52 kV; about 400–4,000 A; 16–63 kA; fused, breaker or contactor lineups

LV outdoor boards through 1,200 kV AIS/GIS; catalogue must segment LV, MV and HV rather than use one rating

LV through 52 kV common indoor switchgear; roughly 630–6,300 A depending class

2.4–38/40.5 kV common; 600–4,000 A; 16–63 kA

3.6–40.5 kV; 630–1,250 A; 16–31.5 kA; commonly 2–6 functional ways

2.4–38 kV; 1,200–4,000 A; 25–63 kA; withdrawable breakers common

LV 208–690 V or MV 2.4–38 kV; 600–6,300 A; internal arc duration/class project-specific

LV compact boards and MV compact/RMU systems; about 400 V–40.5 kV and 250–2,500 A

208–690/1,000 V; 630–10,000 A; short-circuit ratings commonly 25–150 kA

208–690 V; commonly 250–6,300 A; 25–100 kA

120/208/240/400/415/480/600 V; about 63–2,500 A; wall/floor mounted

208–690 V; main bus commonly 600–5,000 A; starter buckets from fractional kW to multi-MW motor feeders
