An influence of new arc quenching methods for improving the interrupting capacity of low voltage circuit breaker

Low voltage circuit breakers are widely used in power distribution systems for rapid interruption of fault currents to assure the reliability of the power supply. While power distribution systems are demanding transformers with higher capacity than ever, there is an increase in the number of short-c...

More Information
Summary:Low voltage circuit breakers are widely used in power distribution systems for rapid interruption of fault currents to assure the reliability of the power supply. While power distribution systems are demanding transformers with higher capacity than ever, there is an increase in the number of short-circuit current accidents. To prevent such accidents, molded case circuit breakers with improved short-circuit current interrupting capacity are needed.
