Circuit Protection Products for Battery Energy Storage Systems
Battery Energy Storage Systems (BESSs) demand a comprehensive circuit protection strategy. Within a BESS, the major areas of concern are protection against electrical overcurrent, ground faults, arc flash, and transient overvoltage. Littelfuse offers products that will protect your system and extend the life of your equipment.

Expanding Energy Storage System Capacity
With 150 kA dc breaking capacity, the Littelfuse PSR series high-speed semiconductor fuse offered the protection the integrator wanted in order to reduce the dc panel count and add more battery units. In addition, by using the PSR square-body fuse (similar to the previous block style fuse form factor) the integrator avoided the cost of making significant design changes.
