FAQ

What is an RCCB used for?

RCCB (Residual Current Circuit Breaker) protects electrical circuits from dangerous earth leakage currents, preventing electric shock and fire risks caused by insulation damage. Suitable for residential, commercial, and industrial wiring systems.

Which is better, RCCB or ELCB?

RCCB is more advanced: it detects all types of residual currents (AC/DC included), while ELCB only monitors earth faults. RCCB offers broader protection and higher reliability, making it the preferred choice for modern electrical systems.

What causes a RCCB to trip?

Common triggers: unexpected leakage current (e.g., damaged wires), overload, equipment insulation failure, or temporary voltage fluctuations. Regular testing ensures proper sensitivity.

Lead time

Varies by region (1-3 weeks for standard models). Contact customer service for details.

Does RCCB support OEM?

Yes, customized services (logo, parameter adjustment) are available. Contact our technical team to discuss requirements.

What certifications does RCCB have?

Compliant with major international safety standards (e.g., IEC, EN).
