What is a residual current circuit breaker?

An RCCB monitors the balance between current flowing through the outgoing and returning conductors. When the residual current exceeds the device operating characteristics, it disconnects the circuit to support earth-leakage protection.

An RCCB is not selected by rated current alone. Pole configuration, rated residual operating current, RCCB type, circuit voltage and coordination with overload and short-circuit protection must also match the installation.

How to choose an RCCB

Use these checkpoints for preliminary comparison, then verify the exact model documentation and installation requirements.

Rated residual current

Match IΔn to the protection objective and applicable installation requirements.

RCCB waveform type

Choose Type AC, A, F, B or another available type according to the connected loads and standards.

การกำหนดค่าขั้ว

Confirm the required 2P or 4P arrangement, circuit voltage and neutral configuration.

Overcurrent coordination

Coordinate the RCCB with the required MCB, fuse or other overcurrent protective device.

RCCB waveform types

Type availability varies by VIOX series. Confirm the product datasheet and applicable installation standard before selection.

RCCB selection questions

Quick answers for comparing a residual-current protection family before detailed circuit verification.

RCCB ป้องกันอะไร

An RCCB detects an imbalance between outgoing and returning current and disconnects the circuit when the residual current exceeds its operating characteristics. It is used for earth-leakage protection in an appropriately designed installation.

Does an RCCB provide overload and short-circuit protection?

An RCCB is selected for residual-current protection and does not normally replace overcurrent protection. The circuit may also require an MCB, fuse or a combined RCBO according to the installation design.

What is the difference between Type AC, A, F and B RCCBs?

The type identifies the residual-current waveforms the device is designed to detect. The correct type depends on the connected equipment, applicable standards and manufacturer documentation; availability varies by VIOX series.

How should RCCB sensitivity be selected?

The rated residual operating current must match the protection objective and the applicable installation rules. Confirm the required sensitivity on the individual model page or datasheet before specification.

Can an RCCB be selected by rated current alone?

No. Rated current, pole configuration, rated residual operating current, RCCB type, circuit voltage and coordination with overcurrent protection must all be checked.
