For small resistance values, the conductor cross-section is adapted to the current.
In case of destruction, the resistor becomes high-impedance, which is why every series is available with a temperature switch. The stated power values were recorded with the resistors in a horizontal position in the air, at a minimum distance of 100mm from the ground. The power values refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.
