Resistive
Inductive

These one-shot mounted thermal fuses operate when the operating or ambient temperature rises above a pre-set level. At that point the organic pellet melts causing the barrel spring to expand from the contacts and opening the circuit.

FEATURES

  • Series D thermal fuse custom mounted into ceramic base.
  • Single operation device. Once activated the electrical circuit remains permanently open until fuse is replaced.
  • Quick Break: When operating or ambient temperature rises above calibration point, organic pellet quickly melts breaking circuit.
  • Cost-Effective: Thermal fuses are among the least expensive circuit protection devices available.
  • Custom Configurations: Please contact us regarding termination options.
