MS / MD Motor Starting Capacitorstechnical dataDischarge ResistorsA discharge resistor may be fitted to amotor start capacitor to prevent electricaloverstress of the capacitor and or for safetyreasons. In accordance with BS5267 andIEC 60252, the resistor value should be suchthat it reduces the voltage on the capacitor,from the line voltage to less than 50V within60 secs.The resistor value may be approximated asfollows:R (kΩ) max. = TRated capacitance µFRated Voltage(d.c.)T120 50000220 32000260 30000280 28000330 26000Value (kOhms) Wattage5.6 2W15 2W33 0.5W56 1W82 2W100 1Wpart numberingPos 1–150 8 0 M S 2 2 A B M A 1 S T D1 2 3 4 5 6 7 8 9 10 11 12 13 14 15mOTOR START080 MS 22 AB M A 1 STDVariants, Pos. 13-15STD=standard design, all other codes arecustomer specific.Terminal Code, Pos. 121 = Double amp tag2 = special variantCapacitance Tolerance, Pos. 11A = -0% +25%, K = ±10%Manufacturing style, Pos. 10M = Moulded caseCase code, Pos. 8-9AA = 38x75, AB = 38x90, AC = 38 x 116Rated Voltage (rms), Pos. 6-712 = 120Vac, 22 = 220Vac, 26 = 260VacType code, Pos. 4-5MS = Motor start single ratingMD = Motor start dual ratingCapacitance code, Pos. 1-3080 = 80µF, 120 = 120µF
