FB2H-63 Disjoncteur miniature
Le Disjoncteur miniature FB2H-63 offre une protection contre les surcharges et les courts-circuits dans la plage de 10 A à 63 A publiée. Ses données de produit vérifiées indiquent une capacité de 10kA Icu ; 7,5kA Ics, 1P/2P et C. La sélection finale doit correspondre au conducteur, à la charge, à la tension de défaut potentielle, au système d’installation et aux règles locales applicables.
Vue d'ensemble du produit
FB2H-63 is a 10kA Icu; 7.5kA Ics miniature circuit breaker covering 10A–63A. It is available with 1P / 2P and C trip options as stated in the product data. For the FB2 plug-in family, confirm the receiving panel and base arrangement; a matching current rating alone does not establish compatibility.
The model data references IEC 60898-1. Standards, certification scope and technical documents must be confirmed for the ordered configuration and destination market.
Principales caractéristiques
Applications typiques
It is intended for AC distribution circuits where the selected current rating, curve, pole arrangement and breaking capacity match the conductor and system study. Typical project contexts include residential, commercial and light-industrial final distribution; suitability depends on the actual circuit rather than the application label alone.
Demandes d’admission et guide de sélection
Use the product-specific values below as a shortlist, then validate the complete circuit design. Product ratings do not replace a fault-current study, conductor calculation, coordination review or applicable installation rules.
| Point de sélection | FB2H-63 option | Ce que le projet doit confirmer |
|---|---|---|
| Rated current | 10A–63A | Coordinate with design current, conductor ampacity, ambient temperature and grouping |
| Trip curve | C | Choose for load inrush and required fault-clearing performance, not by current alone |
| Breaking capacity | 10kA Icu ; 7.5kA Ics | Confirm against the prospective short-circuit current at the installation point |
| Pole arrangement | 1P / 2P | Match supply system and local switching or isolation rules |
| Installation interface | Montage à branchement électrique | Check enclosure, rail/base, terminal and conductor compatibility |
Breaking Capacity
10kA Icu; 7.5kA Ics is the published product value. Confirm the prospective short-circuit current at the installation point.
Trip and Load Behaviour
C is the available trip/protection option. Match it to load inrush and required disconnection performance.
Pole Configuration
Available arrangement: 1P / 2P. Confirm which conductors must be switched and protected under local rules.
MCB or RCBO
An MCB does not replace residual-current protection where an RCD or RCBO is required.
Guide d'achat
- Specify the exact model: FB2H-63.
- State the required current rating within 10A–63A.
- Confirm pole arrangement: 1P / 2P.
- Confirm trip or protection option: C.
- Provide system voltage, expected fault level, destination market, quantity and any document requirements.
Installation and Coordination Checks
- Verify conductor material and cross-section against the circuit calculation and the published terminal range.
- Confirm the prospective short-circuit current does not exceed the applicable breaking rating.
- Check upstream/downstream coordination, enclosure temperature, grouping, altitude and required clearances.
- Installation, isolation, testing and maintenance must be carried out by qualified personnel under applicable rules.

FB2H-63 Product FAQ
What does 10kA mean on the FB2H-63 breaker?
FB2H-63 publishes 10kA Icu and 7.5kA Ics short-circuit values. These describe fault-interruption duty, not its 10A–63A continuous rated-current range.
When should a 10kA plug-in MCB be used?
Only after confirming the prospective short-circuit current, required Ics duty, coordination and panel compatibility. A 10kA label does not make the breaker suitable for every board or fault level.
What is the difference between a 10kA and 6kA plug-in breaker?
The stated short-circuit duty differs, and Icu/Ics values may also differ. Compare the complete verified product data and receiving-panel requirements rather than treating the devices as interchangeable.
Which is better, a plug-in or bolt-on breaker?
The correct mounting style is the one approved for the receiving assembly. FB2H-63 uses plug-in mounting; a bolt-on breaker follows a different mechanical and connection design.
Are 10kA plug-in circuit breakers safe?
They can be suitable when their electrical ratings, base or panel interface and installation instructions all match the application. Product current, curve and breaking capacity alone are not enough to establish compatibility.
Do plug-in circuit breakers go bad after ten years?
There is no universal ten-year failure rule. Condition, loading, temperature, connection quality and fault history matter; damaged, overheated or unreliable equipment should be assessed by qualified personnel.
