Производитель OEM дифференциальных автоматов PXB2Ln-63 RCBO
The PXB2Ln-63 RCBO предоставляет защиту от перегрузок, короткого замыкания и остаточного тока в пределах диапазона значений 6A–63A, указанных в техническом паспорте. При выборе необходимо учитывать напряжение на цепи, конструкцию проводника, поведение нагрузки, прогнозируемый ток короткого замыкания и действующие правила монтажа — а не только номинал в амперах.
Product Overview
PXB2Ln-63 is an RCBO for 230V AC distribution circuits. It combines thermal-magnetic overcurrent protection with residual-current protection in one device. The published range covers 6A–63A, 1P+N, B / C curves and 30mA sensitivity options. The saved model data describes the residual-current or construction type as Type AC / Type A.
The PXB2Ln-63 can be specified as a Type AC RCBO or Type A DIN rail RCBO when its verified 30mA and 1P+N configuration suits the circuit.
The saved model record lists IEC/EN 61009-1 as the applicable standard reference. No certification claim is added beyond the saved model record.
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.

Protection Scope
An RCBO combines overcurrent and residual-current protection; it is not simply an MCB with a different label.

PXB2Ln-63 Product FAQ
What is the PXB2Ln-63 RCBO?
The PXB2Ln-63 combines overload and short-circuit protection with residual-current protection. Its verified range is 6A–63A with 1P+N configurations; the exact ordered option must match the circuit and local rules.
How does the PXB2Ln-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 PXB2Ln-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 PXB2Ln-63 combines both functions in one product, within its published ratings.
Can the PXB2Ln-63 RCBO be used as a circuit breaker?
It can provide the overcurrent and residual-current functions stated for the model, but only when 230V AC, 6A–63A, 6kA 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 PXB2Ln-63 RCBO?
The principal checks are residual-current sensitivity (30mA), residual-current or construction type (Type AC / Type A), trip curve (B / C), pole arrangement (1P+N) and short-circuit data (6kA). Board space, neutral handling, coordination and destination-market rules also have to be verified.
How should the PXB2Ln-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 PXB2Ln-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.
