ESR Fuses Offer a Wider Range of Protection for Battery Racks
The Littelfuse Energy Storage Rack (ESR) series of fuses are designed specifically to protect battery racks from a range of fault currents to help prevent equipment damage or expensive system failures. The 1500 V dc high-speed square body fuse is extremely fast-acting to respond quickly to safeguard the battery module.
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.
With these features, the ESR fuse offers a reliable and wider range of dc over-current protection to battery-powered systems or other devices in energy storage, power conversion, and dc common bus systems as well as hybrid PV-BESS inverters. In addition, the high dc short-circuit capabilities optimize space and deliver cost savings for energy-storage system integrators.
Specifically designed to safeguard evolving battery technologies with fuse circuit protection, the ESR series conforms to the IEC60269-7 battery standard.
