Thermal-links

HU□X Series

HU□X Series

Features

  • It is a non-resettable thermal link that uses a fusible alloy for its thermal element.
  • It is compliant with RoHS2.
  • Extremely simple construction ensures reliability, and hermetically sealed thermal element reduces deterioration with age.
  • It has superior thermal sensitivity.
  • It uses an insulating container.
  • Please feel free to ask us about cutting, forming, and taping of lead wire.
  • Soldering heatproof is improved, and it is the best for the flow soldering.
