- Replacement Models & Cross-Brand Comparison
5.1 Schneider Same-Series Replacements
| Modello | Difference | Application Change |
| A9F18320 | 20UN, C-curve, 3P | For lower load current |
| A9F18332 | 32UN, C-curve, 3P | For higher load current |
| A9F19325 | 25UN, D-curve, 3P | For inductive loads such as motors |
| A9F18225 | 25UN, C-curve, 2P | Single-phase circuit protection |
- Installazione & Note sull'utilizzo
- Before installation, confirm model matches system parameters: check rated current, poles and tripping curve
- Must be mounted on standard 35mm DIN rail for secure installation
- Ensure terminals are tightly connected to avoid overheating
- Inspect breaker status regularly to ensure proper tripping mechanism
- After a fault trip, eliminate the cause before manually resetting
- Raccomandazioni per la selezione
- C-curve is suitable for distribution and lighting circuits; not recommended for frequent-start motors (use D-curve)
- 3P breakers are for 3-phase 3-wire systems; use 4P if neutral protection is required
- 6kA breaking capacity is for general industrial & commercial buildings; use higher-rated types (e.g. H-type 10kA) for high short-circuit current

Key Selection Advice for Replacements
- Direct equivalent: Prefer IC65N 3P C25A (A9F18325) to match original protection characteristics
- Curva di intervento:
C-curve (5–10In): distribution & illuminazione
D-curve (10–14In): motori, transformers to avoid nuisance tripping
- Potere di interruzione:
6IL (N-type): general commercial & residential
10IL (H-type): industriale & large commercial
15IL (L-type): critical systems with high fault current
- Poli:
3P: 3-phase 3-wire (no neutral protection)
4P: 3-phase 4-wire (fase + neutral protection)
- Brand choice:
International (ABB, Siemens): stable, for critical equipment & export projects
Domestic (CINT, Delizioso): conveniente, for general industrial & civil projects
