Most dV/dT filters are designed and developed to cover the vast majority of NEMA frame motor applications through 600 HP at 480 volts. Above that current level a dV/dT filter can be paralleled to achieve the performance of using a single device. For example if 1,500 amps is required, two 750 amp units can be wired in parallel and connected through a common power block on both the line and load side of the filter.
