A direct current (DC ) applications to provide the necessary protection for insurance choice is not as simple as it seems . Alternating current (AC) applications direct current (DC ) applications are much more common . Therefore, what is known about DC fuses , is much smaller than what is known about the AC fuses . AC fuses , DC instead of fuses can be used in direct current applications of thought or knowledge is absolutely wrong. DC circuits to protect the right insurance choice should be made strictly .

DC fuse to make the right selection , system parameters, good recognition and determination of the maximum allowable current and voltage values ​​are required. This case originated solar and wind energy systems and the protection of elements of the system is very important in terms of damage . Photovoltaic solar power plants in the application , taking into consideration the operating voltage , short-circuit current of the panel ( ISC) between 1.5 and 2.0 times the DC fuse selection must be made .
