求翻译：为了更好的保护系统设备，减少短路电流对设备的冲击及破坏，要求塑壳断路器能够快速切断故障短路电流，故障短路电流应在60ms内切断，大于25倍额定电流的故障电流可在10ms内切断；是什么意思？

In order to better protect the system equipment to reduce the impact of short-circuit current and damage the equipment, requiring MCCB short-circuit current can be quickly cut off the fault, the fault within 60ms short-circuit current should be cut off, more than 25 times the rated current of the fa

In order to better protect systems and equipment, reducing short circuit current to the device, called the shock and damage plastic case circuit breakers can be quickly cut short circuit current, fault short circuit current failure should be cut within 60 MS, and more than 25 times the rated current

For the better protection system equipment, reduces the short-circuit current to the equipment the impact and the destruction, requests to model the shell circuit breaker to be able to shut off the breakdown short-circuit current fast, the breakdown short-circuit current should shut off in 60ms, is

In order to better protect the system, reducing the impact of short circuit current on the device and damage requiring molded case circuit breakers can be quickly cut off short-circuit current fault, short circuit current should be cut off within 60ms fault, fault currents greater than 25 times time
