- Analysis of Key Differences
- 차단 용량 등급 (Most Important Difference)
B형 (기초적인): 25kA 차단 용량, suitable for general industrial and commercial buildings and conventional power distribution systems with low short‑circuit current.
F형 (높은): 36kA 차단 용량, suitable for high short‑circuit current applications, such as near transformers, frequent starting of large motors, or heavy‑duty industrial environments.
- Application Selection
| 모델 | 권장 애플리케이션 | Unrecommended Applications |
| CVS100B | 상업용 건물, small factories, civil distribution, secondary distribution | Large industrial plants, near generators/transformers, systems with shortircuit current >25그만큼 |
| CVS100F | 중공업, large motor circuits, primary distribution, near power source | Simple distribution systems with budget constraints and short ircuit current <25그만큼 |
- Other Minor Differences
가격: Type F is normally more expensive than Type B (대략. 10-20%) due to higher breaking capacity.
내부 구조: Type F uses a reinforced arc extinguishing system and contact design to withstand higher short‑circuit energy.
액세서리 호환성: Both are compatible with the same accessories, including auxiliary contacts, 분로 / 저전압 릴리스, Vigi earth leakage modules, 등.
- 선택 가이드
- Calculate system short‑circuit current: Calculate the expected short‑circuit current based on transformer capacity and line impedance, and select a model with breaking capacity ≥ the calculated value.
- Evaluate power supply environment: Prefer Type F when close to transformers or large loads; Type B can be used for secondary / tertiary distribution with low short‑circuit current.
- 향후 확장을 고려: Reserve 10–20% margin for short‑circuit current to avoid insufficient breaking capacity after system expansion.
- Budget balance: Type B reduces cost when safety requirements are met; Type F is recommended for critical circuits to improve reliability.
- 추가 참고사항
Both models comply with IEC 60947‑2 and provide overload and short‑circuit protection.
The TM‑D thermal‑magnetic release has adjustable overload protection (그리고) and short‑circuit instantaneous protection (Im) to match different load characteristics.
The ETS electronic release provides more precise protection and additional functions (예를 들어. 지락, overload alarm), available for both models.
