Answer Posted / mohan
Amps Per KVAR is between 1.1 to 1.3 Amps
for a 300KVAR panel
the current shall be 130 AMPs(and if the capacitors are
auto swithced , then switching surges need to be considered
hence) * 1.5 Times = 585Amps
The nearest breaker size is 630AMPS
It is preferable to use Capcitor duty contactor for
switching
