Abstract:

The breaking capacity of molded case circuit breaker (MCCB) can be improved by series connection and parallel connection between poles.The commonly used DC MCCBs are derived from the AC MCCB through pole to pole short circuit.The short circuit technologies of MCCB are analyzed and summarized based on patents,hoping to be helpful for patent engineers in judging the novelty and inventive step of new technology,and for researchers in exploring innovative ideas for new technologies and applying existing technologies.

Key words: patent, DC molded case circuit breaker (DC MCCB), short circuit, series connection, parallel connection
