Abstract

Owing to the increasing number of intelligent homes (or called smart home), the corresponding cost is much higher. Low voltage circuit breakers are widely used in the intelligent homes to interrupt fault current rapidly and to assure the reliability of the power supply. This paper was focused on understanding the interrupting capability in the current molded case circuit breaker (hereafter MCCB). In order to improve the capability of MCCB, the analytic method of the capability, based on the 3-D magnetic flux analysis, were developed. After all, this paper presented a good agreement between the computational analysis and the test for the newly developed MCCB 460 V/225 A/ 50 kA contact system
