GE Industrial Switchgear: 1940 to Today - RELECTRIC

The Birth of Circuit Breakers – 1940sAdvances and New Product Lines – 1950sAK-2 Line – 1960sSome Issues and Solutions – 1970sVacuum Circuit Breakers – 1980s OnwardsGE Switchgear in The 21st CenturyGE GuardEonConclusionIn the 1940s, GE became the industry leader in electrical switchgear. Their circuit breakers and fuses were one of the most advanced components available. In fact, GE sold the first resettable fuse after WWII. These resettable fuses are commonly referred to as circuit breakers today. Even today, GE electrical switchgear is the leader for innovative design and functionality. GE started with 5kV and 15kV GE Magnablast breakers. These circuit breakers consisted of heavy solenoid coils, as an engineering function designed to close the breakers. Some of the early 15 kV Magnablast switchgear by General Electric includes GE AM-15-150, GE AM- 5-75, GE AM-5-150, GE AM-5-250, GE AM-15-250 AND GE AM-15-500. However, as time and technology progressed, better models were developed, and the original circuit breakers were deemed unreliable for updated standards. The early model AE-1-25 handled about 600 amp. This was then succeeded by the 1600amp AL-2-50, which itself became obsolete as new models...
