Similarly, in the event thatthe feeder breaker Z2 would not clear the fault, themain breaker Z1 will clear the fault in 0.5 s (asabove).508B5089.3 Type SPB Systems Pow-R BreakersI.L. 29-801 Instruction for the Systems Pow-R Breakerand Drawout MechanismSupplementary Instructions for the Sys-tems Pow-R Breaker used with the DigitripRMS Trip UnitsTypical Time-Current CharacteristicCurves for Type SPB Systems Pow-RBreakerInstantaneous (I)Long Delay and Short Delay (LS)Ground (G)SPB Master Connection DiagramI.L. 29-849AD 29-863SC-5623-93 Fault 2The feeder breaker trip unit will initiate the trip in0.03 s to clear the fault; and Z2 will send an inter-locking signal to the Z1 trip unit.

Note theblocking diode D1 is needed so that the feeder breakerscan send interlocking signals to both the main and tiebreakers, without having the tie breaker send itself aninterlocking signal.AD 29-167RSC-5626-93SC-5627-93SC-5628-93FAT'NEffective May 1997
