LittelFuse fuse 400A MEGA 70V-SF51

LittelFuse fuse 400A MEGA 70V-SF51

LittelFuse fuse 400A MEGA 70V-SF51

For the heaviest taps in a 48 V installation: from a battery bank to a large inverter or to the DC main distribution. Nominal voltage 70 Vdc, breaking capacity 2500 A, and a cold resistance of 0.12 mΩ. Built for 48 V systems. The 70 Vdc version offers the required margin above the charging voltage of a 48 V battery bank. A 32 V MEGA fuse must not be used in these installations. Low contact resistance. At 400 A, the voltage drop remains limited to 50.1 mV. This keeps power loss across the fuse low and prevents unnecessary heating of the holder and the terminals.
