Differences between miniature circuit breakers and molded case circuit breakers

1. Moulded case circuit breakers can be connected to thicker conductors, such as those with an area of more than 35 square meters. The miniature circuit breaker is only suitable for connecting conductors less than 10 square meters&# 160;< Br>2. The end of the molded case circuit breaker is connected with a nut, which is easy to compress and has good contact. The miniature circuit breaker adopts smaller compression terminals, which can only be tightened with a screwdriver. The torque is not enough, so it is not easy to compress, and the contact is not good< Br>3. Molded case circuit breaker uses two sets of devices to protect overcurrent and short circuit respectively, and the action value of overcurrent protection can be manually adjusted. The miniature circuit breaker shares a set of devices for overcurrent and short circuit, and the current is not adjustable&# 160;< Br>4. The molded case circuit breaker has a large phase to phase distance, an arc extinguishing housing, and a strong arc extinguishing capacity. It can withstand greater short-circuit current and is not easy to cause interphase short circuit. It also has a long life&# 160;< Br>5. The action sensitivity of miniature circuit breaker is higher than that of molded case circuit breaker< br>
