Tubolar ceramic support
The RCPO is an undulated rectangular wire resistor wound on a ceramic tubular support and coated with inorganic phosphate cement. The purpose of the coating is to (1) ensure the mechanical protection of the wire, (2) allow a uniform heat distribution and (3) limit thermal expansion of the coils. The coating does not have an electrical insulation function. The greater heat exchange surface area, due to the winding with ribbed rectangular wire, allows reaching higher values of dissipated power. The RCPO is not available in the low inductance version. It is available in the version with adjustment slider, in this case, it is called RCPOR.

In what sectors is this resistance used?The main areas of application are industrial automation, energy and railway sector.
For what types of applications is it used?The product is used: as a dynamic terminating resistor, as a basic element in harmonic filter circuits, as a basic element for neutral earthing resistors, as a resistance to start up motors, as a charge and discharge capacitor resistance in RC circuits as a base element for resistive loads.
What are the electrical specifications?The RCPO family has 11 models with power ratings from 152 W to 1500 W and the ohmic value ranges between 0,068 Ω and 120 Ω. The maximum voltage of use varies depending on the model.
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 non-repetitive pulses the relation is 5 times the nominal power for 10 seconds.
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 of the data sheet on page 2 shows the relationship between the temperature on the resistance and the power applied for a heating element placed horizontally.
