6. series ACB DH Series DB series Tr a Saved Space No extra arc space required a vertical stacking permitted The DH series ACB dissipates all arc energy within its unique Double Break arc chamber The internal energy dissipation within the ACB allows the clearance distance of the ACB to nearby earthed metal to be zero This will assist in minimizing switchboard height and costs ee No extra arc space E required A high performance and reliability Very fast interruption by Double Break system The unique Double Break main contact system ensures extremely fast interruption of short circuit currents and substantially reduces main contact wear The internally symmetrical Double Break structure allows reverse power connection Enhanced selectivity i At Fuji we are so concerned about selectivity that all our protection relays have LSI characteristics as standard This provides an adjustable time delay on overload L and also the t ramp characteristic S As shown these are essential to provide selectivity when grading with other protective devices such as downstream fuses and upstream relays The standard LSI curve provides more than five million combinations of unique time current characteristics Zone selective interlocking is available to provide zero time delay selectivity As the rated breaking capacity is identical to the rated short time withstand current
