ESR Series: Battery Protection Fuses with High DC Interrupting Rating Designed for Power Conversion Systems
![Energy Storage Rack (ESR) Series](/sites/default/files/components/ESR-Series-Battery-Protection-Fuses.jpg)
Littelfuse, Inc. 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. This 1500V direct current (DC) 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 and hybrid photovoltaic battery energy storage system (PV-BESS) inverters. Moreover, this ESR series conforms to the IEC60269-7 battery standard.
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
-
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 size saves space and offers design flexibility
