2TC49 Series“Dual Safety” Circuit BreakersFeatures• Extension of 2TC series• Redundant protection in hard faultcatastrophic conditions• Separable link feature• Case color distinguishes 2TC49 from 2TC series• Uses less space and weighs less than othercircuit breaker packages• Rating 2 1 ⁄2 -15 amps2TC49“Dual Safety” Circuit BreakerOverviewThe 2TC49 “Dual Safety” circuitbreaker represents a refinementin electrical control and circuitprotection. The 2TC dual safetycircuit breaker incorporates afusible element in a standard 2TC(MS 3320) package size toprovide redundant protection inhard fault conditions.“Hard Fault” TrippingThe 2TC dual safety circuitbreaker operates identically to astandard circuit breaker under allnormal conditions, includingshort circuit. In the event ofcircumstances which disable theinternal circuit breakermechanisms, such that the deviceis able to carry current but unableto clear an overload via its normalmeans, the dual safety elementacts as a built in fuse to provideredundant circuit protection.The key part in the dual safetydesign is a two part currentcarrying element joined by aspecial alloy. The geometry andmaterial of the element determineits heating properties. Theelements heating properties areslower than the bimetal sensorbut faster than the smoke curveof the wire the rating is designedto protect. In the case where thestandard mechanism is disabledor cannot operate normally, theseparable element “fuses” open,interrupting the current.The benefits of the dual safetydesign result in calibratedovercurrent protection (basedon fuse times) and specified postfuse dielectric properties forsystem and human protection.

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.

Traditional circuitbreakers were only designed todetect over-current (I 2 t)conditions. However, manyserious electrical incidents arecaused by low level arc faultconditions resulting fromdamaged or aging wire whichpresent generation circuitbreakers are not designed todetect or protect against.Sensata recognizes the evolvingrequirements of the aerospaceindustry and the need forsupplemental arc fault protection.Sensata developed a small,lightweight package configurationbased around proven Klixon®commercial and mil-spec circuitbreaker designs, integrating thetraditional over-current trip featuresof today’s circuit breakerswith new supplemental arc faultdetection and protection features.shut down for motor, fan, strobelight, or fluorescent light.The two arc fault catalog pagesrepresent the first generation ofarc fault circuit breakers that willbe used in the commercialaerospace market. The firstgeneration design is based uponthe industry need to support120VAC, 400 Hz aircraftapplications.Future design considerations forthe arc fault circuit breakersunder development by Sensatacomprehend and include:• Arc fault trip indication• 28VDC• Operating temperature rangeexpansion• Single phase 30–100A• Three–phase development• Ground fault detection• Variable voltage andfrequency optionsAmbient TemperatureCompensationThe arc fault series of circuitbreakers are based on the designof our existing ambient compensatedcircuit breakers productfamily permitting systemdesigners to specify smallergauge wire where the circuitbreaker and wiring are exposedto different ambienttemperatures. The arc faultcircuit breakers can operate overa temperature range of-54 o C to 71 o C however, careshould be taken to understandthe specification limits at elevatedambient temperatures.Trip FreeThe complete line of arc faultseries circuit breakers is tripfree. The circuit breaker cannotbe maintained closed during anoverload, even when the actuatoris held closed.High Short Circuit CapacityThe arc fault series of circuitbreakers offers unusually highshort circuit current interruptingcapacity.

Simplified Glossary of Circuit Breaker TermsCircuit breaker– A devicedesigned to carry a specific valueof current and automatically opena circuit upon overloads orshort circuits.Thermal circuit breaker –A circuit breaker that senses acurrent overload based on thermalheating of the sensing element.Time-current curve – An approximategraph showing the minimumand maximum time a specificbreaker will take to trip on variousdegrees of overload.Ambient compensation –A feature of some thermal breakersthat limits or eliminates thermalderating due to ambienttemperature.Minimum ultimate trip – Currentrating at which a breaker will nottrip within a certain period (usually1 hour) at a specified temperature.Maximum ultimate trip – Currentrating at which a breaker must tripwithin a certain period (usually 1hour) at a specified temperature.Thermal derating – Tendency of abreaker to trip at lower currentlevels due to higher ambienttemperatures, and to trip at higherlevels due to lower ambienttemperatures.Trip-free – Feature of certainbreakers that makes it impossible tohold the breaker closed against anoverload.Manual reset – Method ofaccomplishing reclosure aftercircuit interruption has occurred.Indicating, non-indicating –Whether or not breaker givesprominent visual indication ofopening, such as exposing a whiteband around button, or movingtoggle to off position.Manual trip – Ability of breakerto be opened manually.Auxiliary circuit – An integrallyhoused, electrically independentswitch linked mechanically tooperate with the main circuitbreaker contacts.Voltage drop – The voltagedecrease across the breaker due tointernal resistance of the device.WARRANTYSensata Technologies warrants its circuit breakersagainst faulty workmanship or the use ofdefective materials for a period of 18 monthsfrom date of manufacture.
