3SB Series Simulator Circuit BreakersFeatures• Low amperage / fast trip response• High performance• Packaged in Military Standard configuration• Tactile feel equivalent to industryaccepted aircraft circuit breakers• Lower total system cost3SB23SB4OverviewThe 3SB Series Simulator CircuitBreaker has been developed bythe Precision Products Group ofSensata Technologies to meet thegrowing needs of the commercialand military simulator industry.With more and more training nowbeing conducted on simulatorsdue to the high operational costsof live training, the realism andcomplexity of tomorrow’ssimulators will require a circuitbreaker that can provide the same“look and feel” of industryaccepted circuit breakers,creating a superior trainingenvironment.3SB electromechanical devicesprovide fast trip response withlow current draw at 28 VDC, andare packaged in a standardMS26574 style thermal circuitbreaker configuration foradaptability to aircraft cockpitpanel mounting. This fasttrip/low current performanceprovides the opportunity forsystem level savings by enablingthe designer to potentially downsize the system power source.This eliminates expensive I/Oboards or other electronics whilealso reducing the amount ofcabling required.Changes in training schemesnormally entail system rewiringto reconfigure the simulator,which becomes labor intensiveand costly. With theincorporation of the 3SB device,training changes can easily beachieved through systemsoftware, without the time andcost associated with rewiring.Sensata’s simulator circuit breakersalso provide the same tactile feelas standard MIL qualifiedbreakers to achieve superiortraining realism.Klixon circuit breakers offer theflexibility of ordering replaceableampere rating inserts. They areattached to the top of the pushbutton actuator, to match thecurrent rating used in the actualaircraft. These inserts can berotated within the push button tomeet your cockpit configurationneeds. An optional auxiliaryswitch for remote indications,along with a variety ofconnection alternatives, are alsoavailable.
