Construction and execution RFP
The RFP resistors are groups composed of a resistance type SRF 600/900/1300 inserted in an additional metallic protection equipped with a heat sink and are made with an IP00 environmental protection level. All these groups are cooled in a condition of natural ventilation.

RFP resistors can be equipped with a thermo-switch (RFPT).
