Fuses

self-control fusebattery protector15 A36 VDC3-terminal SMD4-cell battery

WSFB1514 is a 15 A, 3-terminal SMD self-control fuse for 4-cell battery packs. It provides irreversible overcurrent protection and can be heater-triggered by an external sensing circuit for overvoltage protection.

Best for

  • 4-cell battery packs requiring secondary irreversible protection
  • Battery systems with an external overvoltage sensing and heater-drive circuit

Avoid if

  • Applications requiring a resettable protection device
  • Constant or repeated fault conditions

Check before use

  • Validate prospective fault current and DC voltage
  • Validate heater wattage and fuse opening time at the expected ambient temperature
  • Do not use ultrasonic or immersion cleaning
