Product overview
This CHINT NXB-125G listing provides overload and short-circuit protection for AC distribution. Select the exact manufacturer model, pole count, rated current and trip characteristic, then match the installation fault level.
Technical selection summary
| Manufacturer model | NXB-125G |

| Current choices on this page | 63, 80 or 100 A for 1P–4P; 125 A only for 1P/2P |
| Pole scope | 1P, 2P, 3P or 4P; confirm complete neutral/terminal construction |
| Trip characteristic | B / C / D; use the exact manufacturer release/curve row |
| AC supply reference | AC 230/400 V, 50/60 Hz in the NXB-125G manufacturer table; match the exact pole row |
| Short-circuit reference | 10 kA catalogue short-circuit value; 7.5 kA service value in the matched table |
| Installation / documents | 35 mm DIN rail; apply the exact manufacturer installation/derating instructions and obtain documents for the supplied version |
63, 80 and 100 A are documented for 1P–4P; 125 A is documented only for 1P/2P. Do not select 125 A for 3P/4P. A special OV-marked construction requires separate exact manufacturer information and is not established by this B/C/D selection. Apply the manufacturer cabinet-temperature and adjacent-device derating.
