WSB5L Series 1P+N RCCB Residual Current Circuit Breaker
The WSB5L Series 1P+N RCCB (Residual Current Circuit Breaker) is a new-generation protective device designed for AC 50Hz distribution lines with a rated voltage of 240V/400V and rated current up to 63A.
When leakage current exceeds the preset threshold or in the event of an electric shock, the device automatically disconnects power within milliseconds, effectively preventing injury and equipment damage. In addition to earth leakage protection, it also features built-in overload, short circuit, and overvoltage protection, ensuring total system safety.
Constructed from high-impact resistant and flame-retardant materials, the compact RCCB unit is ideal for installation in distribution boxes, control cabinets, and consumer units. Its advanced internal structure guarantees stable performance, long service life, and reliable operation under normal and fault conditions.
Whether used in modern housing developments, industrial control panels, or energy management systems, the WSB5L 1P+N RCCB delivers efficient and safe power distribution protection in a compact, easy-to-install design.
