Features
  • • Fuse-type wire resistor
    • The fuse resistors trip instantly when mains voltage (230Vrms) is applied, without flames or explosions.
    • The resistance wire is wound onto a capped ceramic core and welded to the caps.
    • A special lacquer absorbs the metal vapor in the event of wire vaporization, preventing arcing and thus short circuits.
    • The winding wire is dimensioned for all resistance values ​​between 10 ohms and 330 ohms (100 ohms for the 251-4 package) so that vaporization occurs at mains voltage.
    • The resistance elements are coated with silicone lacquer and are not electrically insulated in the conventional sense.
    • For resistance values ​​below 10 ohms and at other voltages, it is ensured that the resistor cannot catch fire.
    • However, the tripping function must be tested in each individual case.
