Electrical Ratings & Bank Weights

RATINGS: The continuous current ratings are based on a 375°C temperature rise. The resistance values aremeasured at 25°C and have a + 10% tolerance.

CUSTOMDESIGNS: The above table contains our standard selection of grid bank designs. These banks cover a wide range of resistance and current values and contain numerous fixed taps for maximum flexibility. Other variations are available for any application, including customs lengths, widths and tapered designs. Tapered resistor banks, which are normally used for motor starting, contain grids with different current ratings to reduce size and cost.
