Disjuntor Miniatura PXB6-63
O PXB6-63 miniature circuit breaker provides overload and short-circuit protection within the published 6A–63A range. Its verified product data lists 6kA Icu = Ics, 1P / 2P / 3P / 4P and B / C / D. Final selection must match the conductor, load, prospective fault current, installation system and applicable local rules.
Visão Geral do Produto
PXB6-63 is a 6kA Icu = Ics miniature circuit breaker covering 6A–63A. It is available with 1P / 2P / 3P / 4P and B / C / D trip options as stated in the product data.
The model data references Version A: IEC 60898-1; Version B: IEC 60947-2; GB/T 10963.1 and lists CCC certification. Standards, certification scope and technical documents must be confirmed for the ordered configuration and destination market.
Principais Características
Aplicações 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.
Guia de Candidaturas e Seleção
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.
| Ponto de seleção | PXB6-63 option | O que o projeto deve confirmar |
|---|---|---|
| Corrente 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 |
| Capacidade de corte | 6kA Icu = 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 | 45mm terminal-centre reference | Check enclosure, rail/base, terminal and conductor compatibility |
Breaking Capacity
6kA Icu = Ics 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.
Guia de Encomenda
- Specify the exact model: PXB6-63.
- Indique a corrente nominal exigida entre 6A e 63A.

- Confirm trip or protection option: B / C / D.
- Provide system voltage, expected fault level, destination market, quantity and any document requirements.
Verificações de Instalação e Coordenação
- 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.
- A instalação, isolamento, teste e manutenção devem ser efetuados por pessoal qualificado ao abrigo das normas aplicáveis.

PXB6-63 Product FAQ
What does the 6kA rating on the PXB6-63 MCB mean?
It is the published short-circuit breaking capacity, stated as 6kA Icu = Ics for the relevant product data. It does not describe normal circuit loading.
What is the difference between a 6A MCB and a 6kA MCB rating?
6A is a rated-current value for normal load and conductor protection; 6kA is 6,000A of short-circuit interrupting capacity under stated conditions. They describe different functions.
How many amperes is 6kA?
6kA equals 6,000A. This is a fault-current value, while PXB6-63 continuous rated-current options are published separately as 6A–63A.
What is the main difference between 6kA and 10kA breakers?
The main difference is the stated short-circuit breaking capacity. Select the required level from the prospective fault current, product standard and coordination study.
Would a higher kA breaker always be better than PXB6-63?
Not by itself. A higher verified duty may be required for a higher fault level, but curve, rated current, poles, voltage, standard, dimensions and coordination must also match.
Does kA determine the maximum normal load of a breaker?
No. kA relates to short-circuit interruption. Normal load is governed by the ampere rating, conductor design, installation conditions and applicable rules.
Confirm the Right PXB6-63 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.
