The AC Residual Current Circuit Breaker with Overcurrent Protection (RCBO) is an essential safety device designed to protect against electrical hazards and prevent equipment damage. This advanced circuit protection solution combines residual current detection with overcurrent protection in a single compact unit.
Our RCBO features a clear red/green indicator for immediate visual confirmation of operational status, along with finger-protected terminals that prevent accidental contact. The device is constructed with fire-resistant plastic components that withstand abnormal heating conditions and mechanical impacts.
The breaker automatically disconnects the circuit when leakage current exceeds the rated sensitivity threshold, providing reliable protection independent of power supply fluctuations. Its robust design includes a two-step snapping mechanism for secure mounting on standard 35mm DIN rails.
Key protection functions include earth fault detection, leakage current protection, overcurrent protection, and overvoltage protection (OVP). The RCBO is suitable for both terminal and busbar connection methods, offering flexibility in various installation scenarios.
With multiple tripping curves available (B/C/D), the RCBO can be precisely matched to different load characteristics. The device maintains reliable operation across a wide voltage range from 230V to 440V AC.
Manufactured to meet international safety standards, our RCBOs undergo rigorous quality control to ensure consistent performance and long service life in demanding electrical environments.
