What is an RCBO?
An RCBO combines residual-current detection with overload and short-circuit protection in one device. It can disconnect the circuit when earth leakage or an overcurrent fault exceeds the device operating characteristics.
Selection must consider both protection functions. Rated current, breaking capacity, pole arrangement, trip curve, rated residual operating current and residual-current type must match the circuit and connected load.

How to choose an RCBO
Check the overcurrent and residual-current characteristics together, then verify the exact product datasheet.
Jmenovitý proud a vypínací charakteristika
Match the circuit load, conductor capacity and expected inrush behaviour.
Vypínací schopnost
Choose a rating suitable for the available prospective fault current.
Citlivost na zbytkový proud
Match IΔn and residual-current type to the protection objective and connected equipment.
Konfigurace pólů
Confirm the protected poles, neutral arrangement and circuit voltage.
Combined protection functions
Exact functions and ratings vary by series. Confirm all protection characteristics on the product page or datasheet.

RCBO Selection Questions
Rychlé odpovědi pro předběžné porovnání produktových řad před podrobným ověřením obvodu.
What protection does an RCBO provide?
An RCBO combines residual-current protection with overload and short-circuit protection. The exact ratings and residual-current characteristics vary by model.
How is an RCBO different from an RCCB?
An RCCB is selected for residual-current protection and normally requires separate overcurrent protection. An RCBO combines residual-current and overcurrent protection in one device.
Which RCBO ratings should be checked?
Confirm rated current, poles, circuit voltage, breaking capacity, trip curve, rated residual operating current and residual-current type.
Can every RCBO be used on a DC circuit?
No. Use only a model whose voltage, polarity, poles and AC or DC ratings are explicitly suitable for the circuit.
Does RCBO type matter with electronic loads?
Yes. Connected electronic equipment can affect the residual-current waveform, so the correct device type must be selected from the product documentation and applicable installation rules.
