INTEGRATED FUSE HOLDER FOR FRONIUS ECO
/ Due to integrated fuse holders
, fuse based overcurrent protection can be i mplemented directly within
the inverter. When ordering your inverters, you can choose whether the positive pole is populated with
six 15 A* / 1,000 V 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 up to 20 kA. Furthermore, the plug-in modules
allow individual fuses to be quickly replaced in the event of a fault.
*You can also install 20 A fuses, for more information please refer to the operating instructions.
