Thermal links

37 Series

37 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.
  • Halogen free 37MT is available.
  • Please feel free to ask us about cutting, forming and taping of lead wire.

※Uchihashi Estec Co.,Ltd. provides customers with “Halogen free” products that comply with following conditions.

The definition of “Halogen free”: Neither bromine (Br) nor chlorine (Cl) is intentionally added in a thermal links itself. The concentration of bromine or chlorine shall not individually exceed maximum of 900ppm. And the total concentration of bromine and chlorine shall not exceed maximum of 1500ppm.

  • Functioning temperature is measured with silicone oil bath of which temperature is increased at the rate of 1℃/min. Detecting current is 0.1A or less.
  • Please feel free to contact us in regard of the details of safety standard approvals.
