High speed fuses – Superior protection for batteries
How to protect critical battery storage systems?
The answer is – with high speed fuses.
Compared to AC circuits, the absence of natural voltage zero in a DC circuit makes it more difficult for a fuse to interrupt the current at fault. Battery protection is a specific area of DC applications with special requirements. Compared to the operational current is the prospective short circuit current relatively low, however it should be interrupted in less than 5 s. Longer interrupting time may result in overheating and damage the batteries.
Another factor to concern is the voltage level, larger battery storage system normally operates at higher voltages, up to 700 VDC.
Upgrading the standard gG fuses to a high speed gR fuses offers improved protection. The fuses can be used at higher DC voltages compared to gG fuses.
