Natural cooling Use rated current I~R and ambient temperature TA. 2. Cooling of base Use rated current I~R (B) and temperature of capacitor base TB. 3. Cooling of terminals and base Use rated current I~R (T+B) and temperature of capacitor base TT+B. Ensure that the temperature of the cooled terminals is lower than that of the case base. Due to the current load capability of the contact elements, the following current limits must not be exceeded, even if the frequency and temperature factors have been taken into account: Capacitor diameter Capacitor base cooling 64,3 mm 62 A Terminal and capacitor base cooling 75 A 76,9 mm 80 A 100 A 91,0 mm 80 A 100 A 1) Refer to page 40 for an explanation on how to interpret the useful life graphs. 164 10/02 B43750 / B43770 Max.
