RFZ 200
RFZ 200
Wire coiled inserted in ceramic tube and filled with quarzite sand, sealed by silicone plug
The RFZ is a resistance made of an aluminium dissipater with coiled wire inserted in perforated ceramic and filled with quartzite sand. The metal case is sealed with silicone elastomer; this guarantees a minimum IP54 degree of protection.

In what sectors is this resistance used?
The main areas of application are industrial automation and the energy sector.For what types of applications is it used?
The product is used: as a charge and discharge capacitor resistance in RC as heating resistances for electrical or anti condensation panels.What are the electrical specifications?
The RFZ family has 5 models with power ratings from 80 W to 220 W and the ohmic value ranges between 0.56 Ω and 18KΩ. The nominal voltage of use is 600 V.What are the overload conditions?
The resistance can be overloaded with respect to its nominal power based on the working cycle (insertion and rest time). For duration pulse less than one second, the overload permissible also depends on the ohmic value. For pulses of longer duration, the internal quartzite plays a decisive role in dissipating energy.What is the temperature of the resistance?
The temperature of the resistance depends on the power that it will dissipate. Numerous factors influence the dissipation capacity; please consult our technical data sheet for detailed information. The graph on page 2 of the data sheet shows the relationship between the temperature on the casing and the power applied for a heating element placed horizontally.
The resistance can be installed horizontally or vertically, in this case it is necessary that the cables are facing downwards. For mounting, use the two slots at the ends. The provided cables that have not been stripped are used for electrical connection. The dissipater provided is not anodized.
