RFZ/C 100

In stock

resistor in aluminium case
The RFZ/C 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. Model RFZT/C is identical to model RFZ/C with the addition of the thermal pad.

1. In what sectors is this resistance used?
The main areas of application are industrial automation and the energy sector.
2. For what types of applications is it used?
The product is used: in RC circuits as resistance of charging and discharging capacitor, as the dynamic braking resistor.
1. What are the electrical specifications?
The RFZ/C family has 6 models with power ratings from 75 W to 240 W and the ohmic value ranges between 1.1 Ω and 220 Ω. The nominal voltage of use is 100 V.
2. 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.
3. 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.
1. How must I install the product?
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 cable that has not been stripped is used for electrical connection. The dissipater provided is not anodized.
