- Modelli sostitutivi & Cross-Brand Comparison
5.1 Schneider Same-Series Replacements
| Modello | Differenza | Application Change |
| A9F18320 | 20UN, Curva a C, 3P | For lower load current |
| A9F18332 | 32UN, Curva a C, 3P | For higher load current |
| A9F19325 | 25UN, D-curve, 3P | For inductive loads such as motors |
| A9F18225 | 25UN, Curva a C, 2P | Single-phase circuit protection |
- Installazione & Note sull'utilizzo
- Prima dell'installazione, 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
- Dopo un viaggio per colpa, 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 & edifici commerciali; use higher-rated types (per esempio. H-type 10kA) for high short-circuit current
