Características clave
Aplicaciones típicas
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.
Guía de Solicitudes y Selección
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.
| Punto de selección | CQB2H-63 option | Lo que el proyecto debe confirmar |
|---|---|---|
| Corriente nominal | 6A–63A | Coordinate with design current, conductor ampacity, ambient temperature and grouping |
| Curva de disparo | B / C / D | Choose for load inrush and required fault-clearing performance, not by current alone |
| Capacidad de corte | 10kA Icn | Confirm against the prospective short-circuit current at the installation point |
| Pole arrangement | 1P / 2P / 3P / 4P | Match supply system and local switching or isolation rules |
| Installation interface | DIN-rail installation | Check enclosure, rail/base, terminal and conductor compatibility |
Breaking Capacity
10kA Icn is the published product value. Confirm the prospective short-circuit current at the installation point.
Trip and Load Behaviour
B / C / D is the available trip/protection option. Match it to load inrush and required disconnection performance.
Pole Configuration
Available arrangement: 1P / 2P / 3P / 4P. 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.

CQB2H-63 Product FAQ
What does 10kA mean on the CQB2H-63 MCB?
10kA is the published rated short-circuit breaking capacity, not the normal load current. It means the device's interrupting duty is stated as 10,000A under the applicable test conditions.
When is the 10kA CQB2H-63 the right choice?
Use a 10kA MCB only when the prospective short-circuit current and the protection-coordination study are within its published duty. A higher rating should not replace a fault-level calculation.
How should kA be interpreted on the CQB2H-63?
kA expresses short-circuit interrupting capacity in thousands of amperes. It is separate from the 6A–63A rated-current options used to select load and conductor protection.
Is 10kA the same as a 10,000A load rating?
No. The 10kA value relates to fault interruption. CQB2H-63 continuous rated-current choices remain within 6A–63A and must be coordinated with the conductor and design current.
What is the difference between a 10kA and 6kA MCB?
The main difference is the stated short-circuit breaking capacity. Choose between them from the prospective fault current, applicable standard, coordination requirements and verified product data—not from price or current rating alone.
Which CQB2H-63 curve and pole configuration should I choose?
CQB2H-63 is published with B, C and D curves and 1P–4P options. Match the curve to inrush and fault-clearing needs and match the poles to the supply, switching, neutral and isolation design.
Confirm the Right CQB2H-63 Configuration
Send your current rating, pole arrangement, trip option, system voltage, prospective fault level, destination market and quantity. CHAC will review the request against the published product range.
