        Abstract: MCCB is widely used in power transmission and distribution of electricity and power supply system. It is the main component of circuit protection. GB/T 14048.2-2008 provides the basic requirements and test methods for circuit breaker. This paper focused on two key tests of tripping limit and characteristics, rated limit and short-circuit breaking capacity of MCCB. The quality problems were analyzed according to the inspection results of product quality supervision and spot check. A pareto diagram for the study of quality improvement method was presented, which provides a theoretical basis for the quality improvement, performance optimization and reliability study of the circuit breaker. An example shows that this method is effective and feasible.
        Key words: circuit breaker; trip limit and characteristic; rated ultimate short-circuit breaking capacity; quality improvement; pareto diagram
