PTC Resettable Fuses

polymer PTCresettable fuse2.50 A hold5.00 A tripthrough-hole120 V AC/DC

TRE250 is a through-hole polymer PTC resettable fuse rated for 2.50 A hold current and 5.00 A trip current at 25°C. It supports 120 V AC/DC operation and is intended for resettable overcurrent protection.

Best for

  • Resettable overcurrent protection in through-hole power circuits
  • Applications needing approximately 2.5 A hold current at 25°C

Avoid if

  • The circuit requires a non-resettable fuse
  • Operating voltage exceeds 120 V AC/DC
  • Fault current exceeds 15.0 A

Check before use

  • Ambient-temperature derating
  • Trip time at the expected fault current
  • Lead spacing and mechanical fit
  • Post-trip resistance impact on normal operation

Questions & answers

TRE250 is a TLC polymer PTC resettable fuse with two radial through-hole leads. It increases in resistance during an overcurrent event and can reset after the fault is removed and the device cools.
