Icu is only 20kA at 600V – use with caution.
- Release settings
Перегрузка (thermal): set to 1.0–1.1 × load rated current
Мгновенный (magnetic): set to 5–10 × In to avoid nuisance tripping while maintaining selectivity.
- Монтаж & wiring
Зафиксированный, front connection; allow depth ≥ 103.5mm.
Use copper busbar/cable rated for 800A; ≥240mm² copper recommended.
- Maintenance & replacement
Regularly verify release settings.
Inspect contacts after short-circuit tripping; replace if needed.
For upgrades, prefer T6S/T6L or XT6N to keep dimensions compatible.

- Replacement Selection Notes
- Product type choice
For direct replacement of an MCCB, choose NSX for identical form factor.
For upgrading to a main incomer, use MT ACB (note larger dimensions).
- Release settings
Long-delay (И): 1.0–1.1 × rated current
Мгновенный (Ii): 5–10 × In (4000–8000A) to match original ABB behavior.
- Отключающая способность
MT08N1, NSX800N/H exceed 36kA for improved safety.
NSX800F is sufficient if Isc ≤ 36kA.
- Mounting space
MT ACB depth ~300mm (much larger than T6N 103.5mm)
NSX matches T6 dimensions for easy retrofit.
- Краткое содержание
Top Recommendation: Schneider NSX800F TMD 800 3P3D F (order No C80F3TM800).
Perfectly matches the ABB T6N800 in type, current, mounting, отключающая способность, and characteristics, with near-identical dimensions for easy replacement.
Alternative: If ACB is required, use MT08N1 3P F MIC2.0+LR 800A (order No 63006), which provides higher breaking capacity but requires more space.
