Simply speaking, it is the difference of size. Not only the frame circuit breaker is bigger than the moulded case circuit breaker, but also the current grade and subsection capability of the frame circuit breaker are bigger than the moulded case circuit breaker. This is the essential difference, therefore the frame breaker and the molded case circuit breaker application situation is different, the frame applies in the superior enters the line, the molded case applies in the frame subordinate. The moulded case Circuit Breaker and the frame circuit breaker are both widely used in circuit breaker products, but many people are not fully aware of the differences between the two, and often make indecision when buying.
Some of my customers often have this problem, so I consulted three senior engineers in the factory according to this problem, and summarized some of their experience in purchasing, here say the difference between the lower moulded case circuit breaker and the frame circuit breaker, as well as the place that needs to pay attention when choosing. The circuit breaker with plastic Shell is characterized by pressing the circuit breaker Shell and frame with plastic, placing the contact and arc extinguishing system in the insulated chamber, to prevent short circuit between phases, ensure the ARC upward spray, to ensure reliable break contact system. The frame circuit breaker uses Modular rocket, divided into the frame, contact arc extinguishing system, manual operation mechanism,
