Littelfuse has launched its Energy Storage Rack (ESR) series of fuses designed specifically to protect battery racks from a range of fault currents to help prevent equipment damage and expensive system failures. The 1,500-VDC high-speed square body fuse is extremely fast-acting to respond quickly, safeguarding the battery module or other devices in energy storage, power conversion, and DC common bus systems as well as hybrid inverters.

“The ESR is a Class aBat partial range fuse with superior short circuit protection and a low minimum breaking capacity — from 300% or three-times the fuse rated current to a maximum DC fault current of 250 kA,” stated Sakthidharan Krishnamoorthy, product manager, Littelfuse Industrial Business Unit. “With these features, the ESR fuse offers a wider range of DC over-current protection to battery-powered systems than other fuses. In addition, the high DC short circuit capabilities optimize space and deliver cost savings for energy storage system integrators.” Fuse Link
