Residual Current Circuit Breakers RCBO Function EBS9BL-40 residual current circuit breaker come with over current protection device. This RCCB is also named as ELCB or RCD or RCBO in short.●The RCBO is eletromagnetic type with high reliability as its function has nothing with the voltage of the power.●With two handles, the circuit breaker and RCD operate separately. When it is over current, only the handle of breaker disconnect. So has the function of judging the error.●With contact indicator (red and green)●With indicative cover where can put the tag (which is used to mark the control circuit)●When fault caused in the circuit, the handle will stop in the central position, which can be used to judge if the breaker cut-off artificially or automatically. When fault is solved, the breaker only can be switched on after the handle is put on the position of "OFF"●Both the cover and handset are with rational curvature, comfortable handles and compact appearance design.Technical Parameter Model nameEBS9BLE-40StandardIEC61009-1Poles1P+NRated current In(A)6, 10, 16, 20, 25, 32, 40Rated voltage Un(V)230/400V AC 50/60HzRated residual operating current30mATripping durationInstantaneous≤0.1sElectro-mechanical endurance4,000 cyclesConnection terminalPillar terminal with clampTripping curveB, CInstallationInstalled on 35mm DIN railFeatures ●Curve B: (3-5In) protect and control circuit against overload and short circuit; protect people and length cables in TN and IT systems●Curve C: (5-10In) protect and control circuit against overload and short circuit; protect resistive and inductive loads with low inrush current.Applicable Working and bus bar connection Ambient temperature-5~+40℃, the average value cannot exceed to +35℃ within 24hAltitude≤2,000mRelative humidity≤95%Pollution levelII.Installation locationMount on the place where has no obvious vibration or impact
