The resistor element is a resistive wire which

is wound in a single layer on a ceramic rod,

with tinned connecting wires of electrolytic

copper welded to the end-caps. The ends of

the resistive wire are connected to the caps by

welding. The resistors are coated with layers

of green color flame-proof lacquer. Overload

protection without risk of fire. Wide range of

overload currents.

For resistors operated in ambient temperatures above 40°C, power rating must be derated

in accordance with the curve below.
