Both Schneider CVS100B and CVS100F are 100A frame molded case circuit breakers in the EasyPact CVS series.
The core differences lie in the breaking capacity class and application scenarios.
- Core Parameter Comparison (415Vと)
| アイテム | CVS100B | CVS100F | Key Difference |
| Ultimate Short‑Circuit Breaking Capacity (ICU) | 25の | 36の | Type F is 44% より高い, with stronger short‑circuit withstand capability |
| Service Short‑Circuit Breaking Capacity (ICS) | 25の (100% ICU) | 36の (100% ICU) | Same ratio as Icu; Type F is more suitable for harsh short‑circuit environments |
| Ics at 440V | 15の | 18の | Type F maintains better breaking performance at higher voltages |
| 定格電流範囲 | 16–100A | 16–100A | 同じ; both support TM‑D thermal‑magnetic releases |
| Pole Configurations | 3P/3d, 4P/4d/3d | 3P/3d, 4P/4d/3d | Same protective pole configuration |
| Release Type | TM‑D (Thermal‑Magnetic), ETS (電子) | TM‑D (Thermal‑Magnetic), ETS (電子) | Same basic protection functions |
| Mounting Type | 修理済み, Plug‑in | 修理済み, Plug‑in | Same mounting compatibility |
| 配線タイプ | Front wiring / Rear wiring | Front wiring / Rear wiring | Same wiring flexibility |
- Analysis of Key Differences
- 遮断容量クラス (Most Important Difference)
タイプB (基本): 25kA遮断容量, suitable for general industrial and commercial buildings and conventional power distribution systems with low short‑circuit current.
タイプF (高い): 36kA遮断容量, suitable for high short‑circuit current applications, such as near transformers, frequent starting of large motors, or heavy‑duty industrial environments.
- Application Selection
| モデル | Recommended Applications | Unrecommended Applications |
| CVS100B | 商業ビル, small factories, civil distribution, secondary distribution | Large industrial plants, near generators/transformers, systems with shortircuit current >25の |
| CVS100F | 重工業, large motor circuits, primary distribution, near power source | Simple distribution systems with budget constraints and short ircuit current <25の |
- Other Minor Differences
価格: Type F is normally more expensive than Type B (約. 10–20%) due to higher breaking capacity.
Internal Structure: Type F uses a reinforced arc extinguishing system and contact design to withstand higher short‑circuit energy.
アクセサリの互換性: Both are compatible with the same accessories, including auxiliary contacts, shunt / undervoltage releases, Vigi earth leakage modules, 等.
- セレクションガイド
- 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.
- Consider future expansion: 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.
- Additional Notes
Both models comply with IEC 60947‑2 and provide overload and short‑circuit protection.
The TM‑D thermal‑magnetic release has adjustable overload protection (Ir) and short‑circuit instantaneous protection (Im) to match different load characteristics.
The ETS electronic release provides more precise protection and additional functions (例えば. earth fault, overload alarm), available for both models.
