- Replacement Models & Cross-Brand Comparison
5.1 Schneider Same-Series Replacements
| 모델 | Difference | Application Change |
| A9F18320 | 20에이, C-curve, 3피 | For lower load current |
| A9F18332 | 32에이, C-curve, 3피 | For higher load current |
| A9F19325 | 25에이, D-curve, 3피 | For inductive loads such as motors |
| A9F18225 | 25에이, C-curve, 2피 | Single-phase circuit protection |
- Installation & 사용법 참고 사항
- 설치 전, 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
- 선택 권장 사항
- 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 & 상업용 건물; use higher-rated types (e.g. H-type 10kA) for high short-circuit current
