What Is an RCCB?

A Residual Current Circuit Breaker (RCCB) is a protective device used to detect leakage current and disconnect the circuit when an imbalance is detected between outgoing and returning current paths. RCCBs are widely used where earth-fault protection is required and are commonly installed in distribution boards, commercial assemblies, EV charging systems, and modern installations with electronic or inverter-driven loads.

⎯⎯ Applications

Where VIOX RCCBs Are Used

Curve D / MPCB

Charging Infrastructure

Type F and EV-oriented variants align with modern charging environments that require more than basic AC-only residual-current protection.

Curve D / MPCB

Charging Infrastructure

Type B and B+ product families support installations where residual-current behavior is shaped by converters, drives, and power electronics.

စက္မႈ

Drives and Power Electronics

Type A RCCBs fit distribution-board applications across commercial facilities, offices, retail spaces, and public-use systems.

Solar

PV and Storage Projects

Type B product lines align with inverter-based environments where DC-related residual-current conditions must be considered.

လူနေ

Home Safety Protection

RCCBs are widely used in residential distribution boards where earth-leakage protection is part of the protective architecture.

Distribution Partners

Structured Product Programs

Multi-type RCCB coverage supports catalog programs that need a coherent product family rather than isolated single-series supply.

STEPS

TIPS

RCCB device type directly affects application compatibility. Type A, F, B, and B+ do not serve the same applications, even when the current range looks similar.

⎯⎯ FAQ

မကြာခဏမေးမေးခွန်းများ

An RCCB detects leakage current and disconnects the circuit when residual-current imbalance is detected.

The difference is mainly in the type of residual-current waveform and application environment the device is designed to handle.

They are commonly used in residential distribution boards, commercial systems, EV charging, PV systems, and installations with electronic loads.

The current live RCCB lineup highlights series covering rated currents from 16A to 100A, depending on model family and type.

 
 

Choose the RCCB type according to the load characteristics, residual-current behavior, application environment, and project requirements.
