Overcurrent Protection Devices: Methods And Device Sizing

Overcurrent protection devices such as fuses, breakers, and others limit the current to the proper rate and disconnect short circuits. The type of overcurrent protection system used and the maximum current passing through the circuit components determine the size of the overcurrent protection system. The design and size of the overcurrent protection system are outlined by national codes. In many countries, the short-circuit current of the array determines the size of the overcurrent protection devices.
