The integrated fuse holders enable fuse based overcurrent protection to be implemented directly within the inverter. When ordering your inverters, you can choose whether the positive pole is populated with six 15A / 1,000V fuses (supplied by Littelfuse/SIBA/Bussmann) or with bolts. The fuse holders on the negative pole are normally equipped with bolts. The types of fuse used have been specially developed to protect photovoltaic modules and operate to up to 20 kA. Furthermore, the plug-in modules allow individual fuses to be quickly replaced in the event of a fault.
