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 | PXB6-63 L/T 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 Icu = 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 | Referensi terminal-pusat 45 mm | Check enclosure, rail/base, terminal and conductor compatibility |
Breaking Capacity
4.5kA 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.
Panduan Pemesanan
- Specify the exact model: PXB6-63 L/T.
- 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.

PXB6-63 L/T Product FAQ
What is an MCB trip curve?
It describes the time-current response and instantaneous magnetic-trip behavior. PXB6-63 L/T offers B, C and D curves for different inrush and fault-clearing requirements.
Which curve is best for the PXB6-63 L/T?
No curve is universally best. B generally suits lower inrush, C moderate inrush and D higher inrush, provided the available fault current can still achieve the required disconnection.
When should the PXB6-63 L/T use a C curve?
C curve is commonly evaluated for circuits with moderate starting current. Confirm the real load profile, conductor protection and fault-loop conditions before selection.
Will a 20A breaker trip exactly at 20A?
Not instantaneously. Thermal trip time depends on how far and how long current exceeds the rating, along with reference temperature and product characteristics.
Does the 80% rule apply to every circuit breaker?
No. The phrase is associated with particular market rules and applications; it should not be treated as a universal IEC requirement. Follow the governing installation standard and circuit calculation.
What is the 125% rule in electrical design?
It commonly describes market-specific treatment of continuous loads or conductor sizing. Apply only the rules that govern the project and do not use a fixed percentage as a substitute for verified PXB6-63 L/T data.
Confirm the Right PXB6-63 L/T 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.
