The model data references IEC 60898-1; GB/T 10963.1. Standards, certification scope and technical documents must be confirmed for the ordered configuration and destination market.
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 | PXB6-125 option | Lo que el proyecto debe confirmar |
|---|---|---|
| Corriente nominal | 10A–125A | Coordinate with design current, conductor ampacity, ambient temperature and grouping |
| Curva de disparo | C / D | Choose for load inrush and required fault-clearing performance, not by current alone |
| Capacidad de corte | 12.5kA Icn; 7.5kA Ics | 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
12.5kA Icn; 7.5kA Ics is the published product value. Confirm the prospective short-circuit current at the installation point.
Trip and Load Behaviour
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.

PXB6-125 Product FAQ
Is 2 AWG wire suitable for a 125A breaker?
No universal answer is safe because AWG ampacity depends on conductor material, insulation, temperature, termination rating, installation method and local code. PXB6-125 uses metric product references; the project designer must perform the final cable calculation.
What conductor size will fit the PXB6-125?
The published product reference associates 125A with up to 50mm² copper, with smaller references for lower ratings. Terminal fit does not prove ampacity; verify conductor calculation, termination data and installation conditions.
Can #4 copper be used on a 100A breaker?
That is jurisdiction- and installation-specific and cannot be confirmed from the breaker rating alone. For PXB6-125, use the published metric terminal reference and the applicable conductor-sizing rules rather than converting by assumption.
What does kA mean on the PXB6-125?
kA describes short-circuit interrupting duty, not rated load current. PXB6-125 publishes 12.5kA Icn and 7.5kA Ics, which must be checked against the prospective fault current and coordination requirements.
When is a higher-breaking-capacity MCB required?
It is required when the calculated prospective short-circuit current and coordination study demand that duty. The published Icn and Ics values must both be considered for the intended system.
How do I choose the correct PXB6-125 breaker?
Confirm 10A–125A rated current, C or D curve, 1P–4P arrangement, operating voltage, fault level, conductor calculation, enclosure conditions, standard and destination-market documents.
Confirm the Right PXB6-125 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.
