RXT 35S PPP RRR 10%

WW/YY (week / year)

Operating voltage 1000 V

CE mark – cURus logo


PPP stands for the rated power

RRR stands for the ohmic value

Installation

Warning: Units must be mounted with at least 150 mm / 5.9 in of available space from the bottom, 500 mm / 19.68 in on the sides and 1000 mm / 39.37 in on top.
4 holes diam. 11 mm / 0.43 in are provided to fix the resistor on the bottom side. Fairfild may provide upon request the brackets to mount the resistor 150 mm / 5.9 in above the ground and the grid to prevent the inlet of external elements from the bottom

Packing

The resistor is packed in a way to preserve incidental damages due to transport.

RRRR Resistance value (nominal at 20°C)


Example

RX/T 50S 12 kW 15R 10%

RX is the name of the product

T means the clixon is provided with the resistor

50S is the model

12 kW is the wattage

15R means 15
Ω that is the nominal ohmic value at 25°C
10% is the tolerance on the ohmic value, in this case the value of the resistor
is accepted when is within 13.5
Ω ÷ 16.5 Ω
