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
