Industry dynamics

In electrical equipment, circuit breakers are an important part of protecting circuits and equipment. According to different application requirements, there are two main types of circuit breakers on the market: frame circuit breakers and moulded case circuit breakers. Although they are functionally similar, there are significant differences in structure, application and performance.

Frame circuit breaker (also known as frame circuit breaker) is an important protection device used in power systems, widely used in industrial, commercial and civil building electrical equipment. They not only effectively protect electrical equipment from overload and short circuit, but also have a variety of functions to adapt to different application requirements. This paper will introduce the basic knowledge of frame circuit breaker in detail, including its definition, working principle, main characteristics, application fields and maintenance.
