CQB3Ln-63 Product FAQ

What is the CQB3Ln-63 RCBO?

The CQB3Ln-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 CQB3Ln-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 CQB3Ln-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 CQB3Ln-63 combines both functions in one product, within its published ratings.

Can the CQB3Ln-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 CQB3Ln-63 RCBO?

The principal checks are residual-current sensitivity (30mA), residual-current or construction type (Type AC / Type A; electronic construction), 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 CQB3Ln-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 CQB3Ln-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.
