In Chinese traditional philosophy, the concepts of yin and yang represent the dialectical relationship between opposites and unity. This is used to express the essence of this circuit breaker. The black and white color design, which involves a strong sense of decoration that departs from the industrial look of most circuit breakers, ensures better integration into the home. The circuit breaker can sense currents as small as 10mA, cutting off electricity immediately and protecting appliances in advance of a larger surge. The ergonomic operating handle makes user operation easier. This product passed 25,000 mechanical live tests and over 10,000 electrical live tests.
