This Class aBat partial range energy storage rack 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.

Features & 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 size saves space and offers design flexibility

Applications:

• Battery energy storage systems (BESSs)
  • Battery Protection Unit (BPU) and battery racks
• Power conversion systems
• Dc common bus systems
• Hybrid PV-BESS inverters
