This is reference value in the case of a special heat-resistant vinyl wire (HIV).
✔
The diameter of an electric wire and allowable current in the case of doing the bundle line of the three
electric wires are shown.
✔
Use it below by the above-mentioned allowable current.

✔
The information in this table is based on rated armature current flowing through three bundled lead wires at
ambient temperature of 40[°C].
✔
When wires are bundled or put into a wire-duct, take the allowable current reduction ratio into account.
✔
At high ambient temperature, service life of the wires becomes shorter due to heat-related deterioration. In
this case, use special heat-resistant vinyl wire (HIV).
