LittelFuse fuse 300A MEGA 70V-SF51

LittelFuse fuse 300A MEGA 70V-SF51

LittelFuse fuse 300A MEGA 70V-SF51

Heavy-duty main protection for 48 V battery banks, for example between battery bank and inverter or to a DC distribution system. Nominal voltage 70 Vdc, breaking capacity 2500 A, and a voltage drop of only 46.9 mV at nominal current. Built for 48 V systems. With 70 Vdc, there remains a margin above the charging voltage of a 48 V battery bank. Where a 32 V MEGA fuse is not permitted, this is the appropriate version in the same form factor. Low contact resistance. The cold resistance of 0.15 mΩ keeps losses and heat generation low. This is a major factor for a fuse that must handle the full power of the battery bank.
