Nominal power ratings for Danotherm GRT resistors range from 3 to 32 kW, and the working voltages are 1000 VAC / 1400 VDC. Depending on the resistor, the overload capacity can reach 10 times the nominal power ratings for a 5-second pulse per 120s cycle or 7 times the nominal power rating for a 10-second pulse per 120s cycle. GRT resistors cool via natural convection.
