Intelligent Fuse Solutions for Battery Systems

  • Ultra-Low Contact Resistance for High Efficiency
  • High Contact Reliability for Low Signals
  • Enhanced Wear Resistance for Long‑Term Contact Integrity
  • Supports Miniaturization and High‑Power Density Design

The Schurter three-terminal fuses STTP 9550 combine conventional overcurrent protection with an actively triggered overcharge protection function, providing an additional layer of safety for lithium-ion battery systems.

In addition to current-dependent interruption, the integrated trigger terminal enables controlled activation in critical operating conditions. This allows reliable disconnection of charge and discharge paths even in the event of protection IC or FET failure.

Gold-plated terminals ensure low and stable contact resistance, high signal integrity, and
excellent corrosion resistance. The compact package supports high-power-density battery pack
designs ranging from 1 to 24 cells.

Applications:
Typical applications include energy storage systems, power tools, UPS equipment, e-bikes, e
scooters, and automated guided vehicles (AGVs). Supported by UL approvals and designed for
redundant protection architectures required by modern battery safety standards, three-terminal
fuses provide a robust and intelligent protection solution for advanced energy systems.
