Wire-wound resistor RCA series

powerwith mounting bracketcemented

We offer standard models in the RCA series and special models in other series. Resistor assemblies can be supplied as open frames, available to OEM's for mounting in their own enclosure, or in indoor/outdoor enclosures according to a specified IP level Wirewound resistors are constructed with: •a tubular ceramic core with 12 possible sizes for the RCA series: 12 models RCA-1 to RCA-12, •a winding of cupro-nickel or chromium-nickel/round or corrugated tape resistance wire, with a low variation of the ohmic value vs. temperature (TCR), or an iron-chromium-aluminum corrugated tape winding, •a coating on the winding wires to keep them in place when the temperature rises and to facilitate heat dissipation – bare wires may be used on special models-, •terminal connections and, optionally, one or more intermediary taps, •optional adjustable lug to adjust the ohmic value, •insulated or uninsulated mounting brackets.
