Detailed Product Description
Our B-Type RCBO Residual Current Circuit Breaker with Overcurrent Protection is engineered to provide advanced electrical safety by detecting residual currents of AC, pulsating DC, and smooth DC types, which are increasingly common in modern installations such as solar power systems, electric vehicle charging infrastructures, and industrial electronics.
This circuit breaker integrates both earth leakage detection and overcurrent protection (overload and short circuit), streamlining your electrical panels by reducing the number of separate protective devices required. With rapid trip response and high sensitivity (typically 30mA), it protects users from electric shocks, prevents fire hazards caused by leakage currents, and secures your electrical assets.
The compact and modular design fits standard DIN rails, enabling quick and hassle-free installation and maintenance. Our RCBOs comply with international IEC 61008 standards and undergo stringent quality testing to ensure operational reliability and long service life.
Ideal for residential, commercial, and light industrial environments, this B-type RCBO is compatible with a wide range of electrical systems requiring protection from both residual currents (including DC faults) and overcurrents, ensuring comprehensive circuit safeguarding.
