Battery fuse                                                                           

ETI is introducing fuse-links specially designed for for protection of battery storage and UPS systems.

Short circuit current
  • Short circuit current depending on battery model, type and capacity, low compared to operating current
  • Short circuit current has to be interrupted in <10 seconds
Required steep characteristics: protection with Battery fuse link required!
Operating current
  • Operating current depends on battery storage specification
  • Battery operation: voltage of DC link circuit decreases to the final discharge votage
Consider maximum current at final discharge voltage for fuse link selection
