What is the difference between moulded case circuit breaker and leakage circuit breaker

Plastic-case circuit breakers are generally used in direct current circuit systems to distribute power or to prevent overload, overvoltage, undervoltage or short circuit in the motor. The short circuit cutting capacity of the MCCB can reach 100KA, and it is generally used as a line that is not frequently switched on and broken.

The leakage circuit breaker is mostly used in AC circuits, and its cutting capacity does not exceed 5KA, for example, when the two-three-phase power line part platform current exceeds the regulations, it will trip, which can prevent electric shock accidents well.
