TYPICAL APPLICATIONS

  

In RSR series, a corrugated alloy tape is wound edgewise or flat onto a ceramic tube which is coated with a silicone cement which is 

compatible with UL standards.  

This ribbed construction puts both sides of the resistive element in contact with air thus creating a convention area four times greater 

than that obtained with normal wire wound resistors.  

These resistors are designed primarily to withstand heavy overload surges upto max 7 times their rated wattage for 10 to 15 seconds 

(max). This characteristic makes them most suitable for controlling motors requiring high dissipation, low resistance values and high 

current capacity.
