Bus Breaker Backup to Feeder Breaker

The Distribution Protection Unit 1500R/2000R (DPU1500R/2000R) has Multiple Device Trip (MDT) mode capability.
When you enable its MDT mode, a DPU1500R/2000R on a bus breaker can be programmed to provide primary
protection for the bus and backup protection to feeder breakers. If the relay protecting the feeder fails, the bus
breaker DPU1500R/2000R provides isolated backup tripping to the faulted feeder breaker without tripping the bus
breaker. Continuity of service will be maintained on all of the unfaulted feeders.

Component Requirements

The DPU1500R/2000R includes the logic and timing elements and the programming flexibility to allow such backup
protection with few additional devices:

•

DPU1500R/2000R for bus breaker (DPU/B)

•

DPU1500R/2000R for each feeder breaker (DPU/Fn*)

•

1 Pickup Auxiliary relay (PA)

•

1 Auxiliary Tripping relay on the bus (Aux/B)

•

Auxiliary Self-Check Failure relay (74/Fn*) for each feeder breaker

n* = Number of feeder
