  • Approved to EN 60742
  • Vacuum cast
  • Two chamber coil
  • Safety class II
  • Protective system IP 00
  • Conditionally short-circuit proof (*bkf) through built-in temperature fuse,
    or not short-circuit proof (*nkf) but protected by external fuse on primary or secondary

Note: If using the conditionally short-circuit proof transformer type (*bkf), no strip conductors may be guided between the primary connecting pins on the component insertion side, because in this area there is an unprotected live soldering terminal.
