FAQ
What is an RCBO
RCBO (Residual Current Operated Circuit Breaker) is a combined protective device integrating residual current protection (against electric shock/fire) and overcurrent/short-circuit protection, designed for low-voltage electrical systems.
What Does an RCBO Do
It detects abnormal residual currents (earth leakage) and automatically trips to cut off power, while also protecting circuits from overloads and short circuits, ensuring electrical safety in homes, offices, and industries.
What is the difference between RCD and RCBO?
RCD (Residual Current Device) only detects residual currents, while RCBO adds overcurrent/short-circuit protection (like a miniature circuit breaker), offering all-in-one safety.
What is the difference between RCCB and RCBO?
RCCB (Residual Current Circuit Breaker) solely provides residual current protection; RCBO integrates RCCB and MCB functions, covering leakage, overload, and short-circuit risks.
What is the difference between RCBO and ELCB?
ELCB (Earth Leakage Circuit Breaker) is outdated, monitoring only earth faults. RCBO is advanced, detecting residual currents and combining overcurrent protection for broader safety.
Lead time
Varies by region (1-3 weeks for standard models). Contact customer service for details.
Does RCBO support OEM?
Yes, customized services (logo, parameter adjustment) are available. Contact our technical team to discuss requirements.
What certifications does RCBO have?
Compliant with major international safety standards (e.g., IEC, EN).
