1. The difference between the size and the size is simply the difference in size. Not only is the frame size of the frame breaker larger than the molded case circuit breaker, but also the current level and segmentation capability of the frame circuit breaker are larger than the molded case circuit breaker. This is an essential difference, so the frame breaker and the molded case circuit breaker are applied differently. The frame is applied to the upper stage and the molded case is applied to the lower stage of the frame. Please enter a picture description
2, the application scene is different in the rated current, the molded case circuit breaker is generally 630A (some new products can reach 1600A), and the rated current of the frame circuit breaker is much larger, generally 630A-6300A (such as DW15 produced by our company) The DW16 and DW17 series frame circuit breakers have met this standard). In addition, the frame breaker is higher than the molded case circuit breaker in terms of segmentation capability. In practical applications, circuits with a particularly high loop or segmentation capability above 800A or circuits requiring more functions should use frame circuit breakers, circuits below 630A, and generally use molded case circuit breakers. Molded case circuit breakers are suitable for branch protection switches. Please enter a picture description
3, other difference frame circuit breaker segmentation ability and function is perfect Molded case circuit breaker is suitable for branch circuit protection switch conclusion: Through the introduction of the above, the difference between frame circuit breaker and molded case circuit breaker has been explained It's very detailed, so you have to choose the circuit breaker correctly, and you should use them correctly. By telling the difference between the two, when you buy a circuit breaker in your home, you know what type of circuit breaker you should need. Don't confuse it when applying it, because it is an item with two different currents. If it is mixed, it is easy to have some accidents.
