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.
- Comparaison des paramètres de base (415V et)
| Article | CVS100B | CVS100F | Différence clé |
| Ultimate Short‑Circuit Breaking Capacity (ICU) | 25le | 36le | Type F is 44% plus haut, with stronger short‑circuit withstand capability |
| Service Short‑Circuit Breaking Capacity (IC) | 25le (100% ICU) | 36le (100% ICU) | Same ratio as Icu; Type F is more suitable for harsh short‑circuit environments |
| Ics at 440V | 15le | 18le | Type F maintains better breaking performance at higher voltages |
| Plage de courant nominal | 16–100A | 16–100A | Même; both support TM‑D thermal‑magnetic releases |
| Configurations de poteaux | 3P/3d, 4P/4d/3d | 3P/3d, 4P/4d/3d | Same protective pole configuration |
| Type de version | TM‑D (Thermal‑Magnetic), ETS (Électronique) | TM‑D (Thermal‑Magnetic), ETS (Électronique) | Same basic protection functions |
| Type de montage | Fixé, Plug-in | Fixé, Plug-in | Same mounting compatibility |
| Type de câblage | Câblage avant / Câblage arrière | Câblage avant / Câblage arrière | Same wiring flexibility |
- Analysis of Key Differences
- Classe de capacité de coupure (Most Important Difference)
Tapez B (Basique): 25kA pouvoir de coupure, suitable for general industrial and commercial buildings and conventional power distribution systems with low short‑circuit current.
Tapez F (Haut): 36kA pouvoir de coupure, suitable for high short‑circuit current applications, such as near transformers, frequent starting of large motors, or heavy‑duty industrial environments.
- Application Selection
| Modèle | Applications recommandées | Unrecommended Applications |
| CVS100B | Bâtiments commerciaux, small factories, civil distribution, secondary distribution | Large industrial plants, near generators/transformers, systems with shortircuit current >25le |
| CVS100F | Industrie lourde, large motor circuits, primary distribution, near power source | Simple distribution systems with budget constraints and short ircuit current <25le |
- Other Minor Differences
Prix: Type F is normally more expensive than Type B (environ. 10–20%) due to higher breaking capacity.
Structure interne: Type F uses a reinforced arc extinguishing system and contact design to withstand higher short‑circuit energy.
Compatibilité des accessoires: Both are compatible with the same accessories, including auxiliary contacts, shunter / undervoltage releases, Vigi earth leakage modules, etc..
- Guide de sélection
- 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.
- Envisager une expansion future: 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 (Et) and short‑circuit instantaneous protection (Im) to match different load characteristics.
The ETS electronic release provides more precise protection and additional functions (par exemple. défaut à la terre, overload alarm), available for both models.
