ESR Series: Battery Protection Fuses with High DC Interrupting Rating Designed for Power Conversion Systems
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
