Eaton Specialty Breaker - Engine Generator Circuit Breakers
Engine Generator Circuit Breakers
The following table lists FG through NG engine generator breakers with the maximum generator kVA and kW rating. Engine generator breakers are applied at 115% of the generator full load current rating (FLA). The maximum kW rating is based on threephase generators at 80% power factor.
