The Zone 1 trip unit will begin to time out, andin the event that the feeder breaker in Zone 2would not clear the fault, the main breaker inZone 1 will clear the fault in 0.5 seconds.Fault 3The branch breaker trip unit will initiate the tripinstantaneously to clear the fault; and Zone 3 willsend an interlocking signal to the Zone 2 tripunit; and Zone 2 will send an interlocking signalto Zone 1.Zone 1 and Zone 2 trip units will begin to timeout, and in the event that the branch breakerin Zone 3 would not clear the fault, the feederbreaker in Zone 2 will clear the fault in 0.3seconds. Similarly, in the event that the feederbreaker in Zone 2 would not clear the fault,the main breaker in Zone 1 will clear the fault in0.5 seconds.For customers whose distribution systemsrequire the added protection of zone selective interlocking (ZSI), we placed the floating design socket plug – with 12 points ofcontact – internal to the breaker, next to thesecondary disconnect contacts providingfor ease of wiring.Zone Selective Interlocking ProvidesPositive System Coordination withoutTime DelaysCutler-Hammer pioneered ZSI, which allows the breaker closest to the fault to tripwithout any preset time delay. Through ahardwired connection between a downstream breaker’s Digitrip Trip Unit and aDS II or DSL II main breaker’s Digitrip TripUnit, a restraining signal is sent upstream.This allows the breaker closest to the faultto trip instantaneously while the remainderof the distribution system remains on line,thus avoiding unnecessary and oftencostly downtime.IMPACC / PowerNet CommunicationsThe floating design socket plug is alsoused when customers require the highlyreliable, comprehensive power monitoringcapabilities provided by the IMPACC /PowerNet communications system.3

Current Limiters Mounting800, 1600, and 2000 Ampere Breakers:Integrally mounted in the drawout breaker.3200 and 4000 Ampere Breakers: Mounted on separate drawout trucks that fit intocompartments of equal size to their compatible breakers and are positioned adjacent to one another.Exclusive Features Fault Interruption. On overloadsand faults within the breaker interrupting rating, the breaker protectsthe limiters. On higher fault currentsexceeding the breaker rating, the limiters protect the breaker. With properly selected and coordinatedlimiters, the breaker itself will clearoverloads and faults within its interrupting rating, leaving the limiters intactand undamaged. The limiters will provide fast interruption of fault currentsbeyond the breaker rating up to amaximum 200 kA rms symmetrical.Single-Phasing Protection. Interlockarrangements trip the breaker wheneverany limiter blows, preventing singlephasing. The breaker cannot be reclosed on a live source unless there arethree unblown limiters on the breaker.There are three blown limiter indicatorson the breaker faceplate, providing avisual indication when a limiter in anyphase has interrupted a fault.Safety Features. Current limiterson Types DSLII-308, DSLII-516, andDSL II-620 Breakers are accessibleonly when a breaker has been completely withdrawn from its compartment.For Types DSL II-632 and DSLII-840Breakers, current limiters are mountedon a separate fuse truck. It is key interlocked with the breaker to preventwithdrawal or insertion unless thebreaker is disconnected.Additionally, many minor replacementfunctions involving the mechanism, control,and/or accessory devices can be easilyaccomplished.True Two-Step Stored EnergyMechanism for Manually andElectrically Operated Breakers“Stored energy” is energy held in waiting,ready to open or close the breaker withinfive cycles or less. The unique cam andspring design provides necessary energyfor a single close-open sequence as wellas the energy for multiple charge-closeoperations such as this possible s means the energy required to openthe breaker is always prestored followinga closing operation.On manually operated breakers, closingsprings are charged by hand. For electrically operated breakers, springs are normally charged by an electric motor but canbe manually charged in the absence ofcontrol power.More InformationFurther information and pricing can befound in PL.22B.01.P.E.5
