قاطع حماية التيار المتبقي PXB6L-63 مع حماية من التيار الزائد – نوع إلكتروني
ال PXB6L-63 RCBO provides overload, short-circuit and residual-current 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.
Product Overview
PXB6L-63 is an RCBO for 230/400V AC distribution circuits. It combines thermal-magnetic overcurrent protection with residual-current protection in one device. The published range covers 6A–63A, 1P+N / 3P+N, B / C / D curves and 30 / 50 / 100 / 300mA sensitivity options. The saved model data describes the residual-current or construction type as Type AC / Type A; electronic construction.
The PXB6L-63 supports 3 phase RCBO projects through its 3P+N RCBO option, alongside a separate 1P+N configuration.
The saved model record lists IEC 61009-1; GB/T 16917.1 as the applicable standard reference. It also lists CCC certification; scope must be confirmed for the ordered configuration.
Key Features
Typical Applications
Typical use is in final or sub-distribution circuits where both overcurrent and residual-current protection are required. The project must still confirm the expected residual-current waveform, sensitivity, neutral arrangement, pole configuration, fault level, conductor size, enclosure conditions and local wiring rules.
Applications and Selection Guide
Use the verified model values below to create a shortlist, then validate the complete circuit. Product ratings do not replace conductor calculations, a fault-current study, coordination review or local installation requirements.

PXB6L-63 Product FAQ
What is the PXB6L-63 RCBO?
The PXB6L-63 combines overload and short-circuit protection with residual-current protection. Its verified range is 6A–63A with 1P+N / 3P+N configurations; the exact ordered option must match the circuit and local rules.
How does the PXB6L-63 RCBO work?
A thermal-magnetic mechanism responds to overload and short-circuit conditions, while the residual-current function monitors imbalance between conductors and trips when the applicable threshold is reached. It does not remove the need for correct earthing, circuit design or testing.
How is the PXB6L-63 RCBO different from an MCB or RCCB?
An MCB provides overcurrent protection but not residual-current protection. An RCCB provides residual-current protection but normally needs separate overcurrent protection. The PXB6L-63 combines both functions in one product, within its published ratings.
Can the PXB6L-63 RCBO be used as a circuit breaker?
It can provide the overcurrent and residual-current functions stated for the model, but only when 230/400V AC, 6A–63A, 6kA Ics and the residual-current requirements all suit the circuit. It should not be treated as a universal replacement for every breaker.
What are the selection limitations of the PXB6L-63 RCBO?
The principal checks are residual-current sensitivity (30 / 50 / 100 / 300mA), residual-current or construction type (Type AC / Type A; electronic construction), trip curve (B / C / D), pole arrangement (1P+N / 3P+N) and short-circuit data (6kA Ics). Board space, neutral handling, coordination and destination-market rules also have to be verified.
How should the PXB6L-63 RCBO be wired and tested?
Use only the diagram and terminal identification supplied for the exact ordered model. Confirm supply direction, protected neutral arrangement, conductor size, torque and isolation procedure, then perform the prescribed test-button and functional checks. Qualified personnel should complete the work under local rules.
Confirm the Right PXB6L-63 Configuration
Send the current rating, poles, trip curve, system voltage, expected fault level, destination market and quantity, plus residual-current sensitivity and type. CHAC will review the request against the published model range.
