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...

They include the following models: 1. Miniature Circuit Breakers (MCB): Miniature Circuit Breakers do not handle currents higher than 100 amps, which makes them suitable for many home and business applications. Once installed, they’re simple to use but not very tunable — you can’t usually adjust their trip settings, for instance. They operate on thermal or thermal-magnetic properties. 2. Molded Case Circuit Breakers (MCCB): These circuit breakers can handle currents up to 2,500 amps, making them a more robust choice for higher-power residential and industrial purposes. With higher amp ratings, their trip load can typically be tuned. What is the difference between MCB and MCCB circuit breakers? MCCBs can handle more voltage, and because of the different requirements set on them, they come in different casing and with different components. Low-voltage circuit b...
