PXB9-63 Series Overload Protection Miniature Circuit Breaker
Itu PXB9-63 miniature circuit breaker provides overload and short-circuit protection within its published 6A–63A range. Selection should be based on the circuit voltage, conductor, load behaviour, prospective fault current and applicable installation rules—not the ampere rating alone.
Gambaran Produk
PXB9-63 is a miniature circuit breaker for 230/400V AC final-distribution circuits. The verified product range covers 6A–63A, 1P / 2P / 3P / 4P, B / C / D curves and 6kA (Icn/Ics) short-circuit data.
For projects that need a 63A miniature circuit breaker, the PXB9-63 MCB range includes 1P through 4 pole MCB configurations.
The saved model record lists EN/IEC 60898-1; GB/T 10963.1 as the applicable standard reference. No certification claim is added beyond the saved model record.
Fitur Utama
Aplikasi Biasa
Typical project contexts include residential, commercial and light-industrial final distribution. Suitability depends on the actual load and circuit study: conductor ampacity, inrush current, fault level, pole and neutral requirements, enclosure conditions and local rules.

PXB9-63 Product FAQ
What is the PXB9-63 miniature circuit breaker?
The PXB9-63 is a miniature circuit breaker that provides overload and short-circuit protection in the published 6A–63A range. It does not add residual-current protection; use a separate RCD or a suitable RCBO when that function is required.
How does the PXB9-63 miniature circuit breaker work?
A thermal element responds to sustained overloads and a magnetic element responds to high fault current. Actual tripping behaviour depends on current magnitude, selected curve, reference conditions and the complete circuit.
What does the PXB9-63 6kA rating mean?
The saved product data lists 6kA (Icn/Ics). This is short-circuit breaking data, not the normal load current. The prospective short-circuit current at the installation point must not exceed the applicable rating.
Which trip curve should be selected for the PXB9-63?
The published options are B / C / D. Selection should reflect normal current, starting or inrush current and the fault current available for timely operation; no curve is automatically best for every load.
How should the PXB9-63 pole configuration be selected?
Available arrangements are 1P / 2P / 3P / 4P. Confirm the supply system and which live conductors—and, where required, the neutral—must be switched, protected and isolated together.
How should the PXB9-63 miniature circuit breaker be installed?
Use the exact product drawing and instructions. A qualified installer should verify voltage, conductor size, terminal torque, fault level, panel fit, enclosure conditions and coordination before energising the circuit.

Send the current rating, poles, trip curve, system voltage, expected fault level, destination market and quantity. CHAC will review the request against the published model range.
