4.1 ABB Upgrades / Замены

4.2 Cross-Brand Equivalents

5. Выбор & Application Notes
6. Breaking capacity matching

Ensure short-circuit current ≤ 36kA@400V; otherwise use T6S/T6L.

Icu is only 20kA at 600V – use with caution.

2. Release settings

Перегрузка (термический): set to 1.0–1.1 × load rated current

Мгновенный (магнитный): set to 5–10 × In to avoid nuisance tripping while maintaining selectivity.

3. Монтаж & проводка

Зафиксированный, front connection; allow depth ≥ 103.5mm.

Use copper busbar/cable rated for 800A; ≥240mm² copper recommended.

4. Обслуживание & 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.

6. Заключение

ABB T6N800-TM800-40000-8000-F-F-3P is a high-performance 800A MCCB with compact size, adjustable thermomagnetic protection, and standard breaking capacity. It is ideal for high-current three-phase circuits in industrial automation. Selection should consider system short-circuit current, требования защиты, and installation space. For better accuracy and selectivity, use higher-breaking versions or electronic releases.

Schneider Replacement for ABB T6N800-TM800-40000-8000-F-F-3P

Key Summary: The ABB T6N800 is an MCCB; Schneider’s NSX series is the best match. If you require an MT air circuit breaker (АКВ), suitable models are also available. Full solutions and technical comparisons below.

1. Product Type Comparison

2. Schneider MT ACB Replacement

2.1 Recmmended Model: MT08N1 3P F MIC2.0+LR 800A

Model explanation:

MT08: Frame size 800A

N1: Breaking capacity 50kA@400V (higher than T6N 36kA)

3П: 3-столб

Ф: Fixed mount

MIC2.0+LR: Thermomagnetic protection (Long + Мгновенный)

800А: Номинальный ток

Parameter matching:

Номер заказа: 63006 (MT08N1 3P F MIC2.0 800A)

2.2 Альтернативы (Higher Breaking)

MT08N2 3P F MIC2.0+LR 800A: 50кА при 400 В, wider current range

MT08H1 3P F MIC2.0+LR 800A: 65kA@400V for heavy short-circuit systems

3. Better Schneider NSX MCCB Replacement

3.1 Рекомендуемая модель: NSX800F TMD 800 3P3D F

Model explanation:

NSX800: Frame 800A

Ф: 36кА при 400 В (identical to T6N)

ДВНЧС: Thermomagnetic release (distribution type)

800: Rated current 800A

3П3Д: 3-столб

Ф: Зафиксированный, front connection

Parameter matching:

Номер заказа: C80F3TM800

3.2 Higher-Breaking Alternatives

NSX800N TMD 800 3P3D F: 50кА при 400 В, order No C80N3TM800

NSX800H TMD 800 3P3D F: 70kA@400V for heavy industry

4. Replacement Selection Notes
5. 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).

2. Release settings

Long-delay (И): 1.0–1.1 × rated current

Мгновенный (Ii): 5–10 × In (4000–8000A) to match original ABB behavior.

3. Отключающая способность

МТ08Н1, NSX800N/H exceed 36kA for improved safety.

NSX800F is sufficient if Isc ≤ 36kA.

4. Mounting space

MT ACB depth ~300mm (much larger than T6N 103.5mm)

NSX matches T6 dimensions for easy retrofit.

5. Краткое содержание

Top Recommendation: Schneider NSX800F TMD 800 3P3D F (order No C80F3TM800).

Perfectly matches the ABB T6N800 in type, текущий, монтаж, отключающая способность, and characteristics, with near-identical dimensions for easy replacement.

Альтернатива: If ACB is required, use MT08N1 3P F MIC2.0+LR 800A (order No 63006), which provides higher breaking capacity but requires more space.
