1 new IEC standard for semiconductor circuit-breakers

Until now, circuit-breakers have relied on the electrical arc generated by the separation ofmetallic contacts to interrupt both normal and fault currents. This principle, introducedover a century ago, has remained the foundation of conventional circuit-breakertechnology. Transistors such as MOSFETs* or IGBTs** have been widely used...
