Note

PCT4000 model numbers are calculated from the power rating of 4 W per inch. The last three digits of the model number represent the
mounting center spacing of the resistors in inches (decimal is between the first and second digit, mounting center spacing is available between
0.50" [12.70 mm] and 2.15" [54.61 mm]. Example: PCT4150 = 1.50 inches x 4 W per inch = 6 W.
