FAQ

What is Type B RCBO

A Type B RCBO (Residual Current Circuit Breaker with Overcurrent Protection) detects AC, pulsating DC, and smooth DC residual currents (up to 1000mA), protecting against faults from modern devices like EV chargers or inverters. It combines overload/short-circuit protection with advanced residual current detection.

What is the difference between Type A and Type B RCD?

Type A RCD: Detects AC and pulsating DC residual currents (common in basic electronics).

Type B RCD: Detects AC, pulsating DC, and smooth DC (e.g., from solar inverters or VFDs), offering broader protection for complex systems.

What is the difference between Type B and Type C RCBO?

Type B: Refers to residual current type (detects AC/DC currents).

Type C: Refers to overload tripping characteristic (5-10x rated current, for inductive loads like motors). They describe different features (residual current vs. overload response).

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.

Can you use Type B RCBO in domestic?

Yes. Type B RCBOs are safe for homes, especially with modern devices (EV chargers, heat pumps). While not always required, they provide enhanced protection against DC faults compared to standard Type A RCBOs.

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).
