Energy Storage Rack (ESR) Fuses
The Energy Storage Rack (ESR) series of fuses are designed specifically to protect battery racks from a range of fault currents to avoid equipment damage or expensive system failures. The high-speed square body fuse is extremely fast-acting to respond quickly to safeguard the battery module or other devices in energy storage, power conversion, and dc common bus systems as well as hybrid PV-BESS inverters.
The ESR is a Class aBat partial range fuse with superior short circuit protection and a low minimum breaking capacity. It offers a reliable and wider range of dc over-current protection for battery-powered systems.
