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 | PXB6M-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: PXB6M-63.
- Indique a corrente nominal exigida entre 6A e 63A.
- Confirm pole arrangement: 1P / 2P / 3P / 4P.
- 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.

PXB6M-63 Product FAQ
What does DIN-rail circuit breaker mean?
It is a modular protective device designed for mounting on a standardized rail in an enclosure. PXB6M-63 is a DIN-rail MCB for overload and short-circuit protection within its published ratings.
Why is it called a DIN rail?
DIN refers to the standards-originated rail format widely used to mount modular electrical equipment. Rail profile alone does not establish electrical compatibility or approval.
How is a circuit breaker attached to a DIN rail?
The device is secured with its designed mounting mechanism on the specified rail. Installation details, orientation, clearance, wiring and safe isolation must follow the product and enclosure instructions.
What is a DIN rail used for in an electrical panel?
It provides an organized mounting support for compatible modular devices. The enclosure must still provide suitable space, environmental protection, conductor routing and heat management.
How do I choose the correct DIN-rail circuit breaker?
Confirm rated current, system voltage, B/C/D curve, 1P–4P arrangement, 6kA Icu = Ics duty, conductor range, coordination and destination-market requirements.
Do all DIN-rail breakers fit all panels?
No. Even when the rail profile is similar, module width, busbar and terminal arrangement, enclosure clearances, ratings and approvals can differ. Verify the complete assembly before installation.
Confirm the Right PXB6M-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.
