Fitur Utama
Aplikasi Biasa
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.
Permohonan dan Panduan Pemilihan
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.
| Titik pemilihan | PXB2-63 option | Hal yang harus dipastikan oleh proyek tersebut |
|---|---|---|
| Rated current | 6A–63A | Coordinate with design current, conductor ampacity, ambient temperature and grouping |
| Trip curve | B / C / D | Choose for load inrush and required fault-clearing performance, not by current alone |
| Kapasitas pemecahan | 4.5kA Icn = Ics | Confirm against the prospective short-circuit current at the installation point |
| Susunan tiang | 1P / 2P / 3P / 4P | Match supply system and local switching or isolation rules |
| Installation interface | Instalasi DIN-rail | Check enclosure, rail/base, terminal and conductor compatibility |
Breaking Capacity
4.5kA Icn = 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.
Panduan Pemesanan
- Specify the exact model: PXB2-63.
- State the required current rating within 6A–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.
Pengujian Instalasi dan Koordinasi
- 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.

PXB2-63 Product FAQ
What does 4.5kA mean on the PXB2-63 MCB?
It is the published short-circuit breaking-capacity value, stated as 4.5kA Icn = Ics. It does not describe normal load current or guarantee suitability at every installation point.
What does the kA rating tell you about PXB2-63?
kA means thousands of amperes of short-circuit current under the applicable test conditions. PXB2-63 rated-current options are separately published as 6A–63A.
Is a higher kA model always better than PXB2-63?
A higher verified rating may be needed where the prospective fault current is higher, but it is not a universal quality score. Select from fault level, coordination, standard, dimensions and project requirements.
Is 10kA the same as a 10,000A continuous current rating?
No. A 10kA value refers to short-circuit interruption, not continuous loading. The conductor and normal load must be matched to the breaker's ampere rating.
What is the difference between 4.5kA, 6kA and 10kA MCBs?
They state different short-circuit breaking capacities. The installation's prospective short-circuit current and coordination study determine the minimum acceptable duty; rated current and curve are separate choices.
How many watts can a 10A MCB supply?
Power cannot be determined from 10A alone; it depends on system voltage, phase arrangement, power factor, load behavior and applicable continuous-loading rules. The circuit and conductor must be designed together.
Confirm the Right PXB2-63 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.
