Ordering information


Y T : External thermal switch 160±5°C (rated voltage: 250 V; rated current: 16 A; leads Faston 6.3)

XXX Model 750, 1100, 1500

RRRR Resistance value (nominal at 20°C)


RDF 1100 15R 5%

RDF is the name of the product 1100 is the model

15R means 15 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 14.25 Ω ÷ 15.75 Ω
