BB1L-63 RCBO Leakage Protection Circuit Breaker
The BB1L-63 RCBO (Residual Current operated Circuit Breaker with Overcurrent protection) is a highly integrated electrical safety device engineered for comprehensive power distribution protection. Covering full pole configurations including 1P/2P (230V) and 3P/4P (380V), this all-in-one breaker seamlessly combines overload, short-circuit, and earth leakage protection into a single compact unit. With a rated current up to 63A, 6kA breaking capacity, and 30mA fast leakage tripping, it is the ideal solution for residential, commercial, and light industrial applications, maximizing panel space while ensuring ultimate electrical safety.
Key Features
- Triple Safety Protection: Integrates overload, short-circuit, and leakage protection in a single device, providing synchronized defense against multiple electrical hazards without the need for separate modules.
- Flame-Retardant Insulating Housing: Constructed with high-grade flame-retardant materials that are highly resistant to high temperatures and aging. The robust shell prevents deformation and combustion during operation, ensuring long-term durability and safety.
- Test Button & Easy Reset: Equipped with a dedicated test button for regular self-checking of the leakage protection function. The fault reset operation is simple and intuitive, ensuring reliable maintenance and operational readiness.
