RS/R 25 150R 5% TC
RS is the name of the product
R means the adjustable version
25 is the model that corresponds, for RS family, to the rated power, in this case 25 W
150R means 150 Ω that is the nominal ohmic value at 20°C
5% is the tolerance on the ohmic value, in this case the value of the resistor is accepted when is within 142.5 Ω ÷ 157.5 Ω

SURFACE TEMPERATURE CHARACTERISTICS
Except where stated otherwise, Rated power is given at 20 °C ambient temperature. The maximum power that can be dissipated decreases with the increase of ambient temperature. Derating drops to zero at 350°C ambient temperature from nominal rating at 25%.
