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 250 kA—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 and Benefits: • 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 • The 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 • Low watt loss maximizes efficiency by preventing energy loss and minimizing the wasted power of components • Conforming to the IEC60269-7 battery standard, the ESR series is specifically designed to safeguard evolving battery technologies with fuse circuit protection • Compact NH 1XL and 3XL sizes save space and offer design flexibility
