According to the application, circuit breakers can be divided into two categories: low-voltage circuit breakers and high-voltage circuit breakers.
Low-voltage circuit breakers:
They are typically used in distribution systems to protect circuits and equipment. Common low-voltage circuit breakers include air circuit breakers, fuses, and ground fault circuit interrupters.
High-voltage circuit breakers:
They are typically used in high-voltage switchgear in power systems. They prevent accidents caused by electrical faults in the power system. Common high-voltage circuit breakers include oil circuit breakers, gas circuit breakers, and vacuum circuit breakers.
