Note 1: 50 Kvar, 100 Kvar, 200 Kvar, 250 Kvar and 400 Kvar three-phase capacitor banks will utilize three-phase capacitor units. All other capacitor banks will use single phase capacitor units.
Refer to Table 6 for standard single phase capacitor units used in MELP capacitor banks.
Refer to Table 7 for standard three phase capacitor units used in MELP capacitor banks.
Note 2: Consult Gilbert Electrical Systems for this rating.
Note 3: Fixed capacitor bank only. Consult Gilbert Electrical Systems for a switched bank alternative.
