Bussman PV FusesOverview of String Protection

Depending on the desired capacity of the Photovoltaic (PV) system, there may be several PV strings connected in parallel to achieve higher currents and subsequently more power.

PV systems that have three or more strings connected in parallel need to have each string protected. Systems that have less than three strings will not generate enough fault current to damage the conductors, equipment or modules. Therefore they do not present a safety hazard, provided the conductor is sized correctly, based on local codes and installations requirements.

Where three or more strings are connected in parallel, a fuse link on each string will protect the conductors and

modules from over current faults and help minimise any safety hazards. It will also isolate the faulted string so that the rest of the PV system can continue to generate electricity.

It should be remembered that PV module output changes with the module temperature as well as the amount of sun it is exposed to. The exposure is dependent on irradiance level, incline as well as shading eff ect from trees/buildings or clouds. In operation, fuse links, as thermal devices, are infl uenced by ambient temperature. The current capability of the PV fuse links should be de-rated according to the Rated Current Dimensioning in the Cooper Bussmann High Speed Fuse Application Guide # 3160 at www.cooperbussmann.com.

1500V Fuses (DC)Eaton’s Bussmann™ series of 14x65mm (10x85mm with 10mm caps) package PV fuses are specifi cally designed for protecting and isolating photovoltaic strings. These fuse links are capable of interrupting low over-currents associated with faulted PV systems (reverse current, multi-array faults).
