ESR Series High-Speed Square Body Battery Protection Fuses • 1500 V Dc • Class aBat • 125 A Description The Littelfuse Energy Storage Rack (ESR) series of fuses is designed specifically to protect battery racks in energy storage systems, inverters, and many other dc applications. The 1500 V dc high-speed square body fuse is extremely fast-acting to respond quickly to a range of fault currents to safeguard the battery module or other devices. This Class aBat partial range fuse has superior short circuit protection and a low minimum breaking capacity (MBC)—from 300 % or 3 times the fuse’s rated current to 175 kA (250 kA self-certified)—to cover a range of over currents that traditional high-speed partial range fuses do not protect against. The ESR fuse safely interrupts most faults in a battery storage system to avoid catastrophic failures and costly shutdowns. Features & Benefits FEATURES High dc interrupting rating Provides superior short-circuit protection and the ability to scale-up systems without the need to redesign the existing circuit protection, saving time and costs Low minimum breaking current Offers easy coordination with battery modules and reduces size and rating of dc contactors to save space and costs Extremely fast acting Delivers high-speed performance Maximizes efficiency by preventing energy loss and minimizing the wasted power of components Conforms to the IEC60269-7 battery standard Specifically design to safeguard evolving battery technologies with fuse circuit protection Saves space and offers design flexibility Battery energy storage systems (BESSs) – Battery Protection Unit (BPU) and battery racks Power conversion systems Dc common bus systems Hybrid PV-BESS inverters Littelfuse.com/ESR ©2022 Littelfuse, Inc.
