B Type RCCB Residual Current Circuit breaker<br> 4Pole Type B RCD RCCB Residual Current Circuit Breaker<br> Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and/or electrocution through automatic disconnection of the electrical supply relies on the of the type of RCCB EKL1-63B.<br> Electrical Features<br> Mode Electromagnetic<br> color: White<br> Material: ABS<br> Type(wave form of the earth leakage sensed) B<br> Rated current In 40A,63A<br> Poles 4P<br> Rated voltage Ue 4P 415V~<br> Insulation voltage Ui 500V<br> Rated frequency 50/60Hz<br> Rated residual operation current(I n) 30mA<br> Rated residual making and breaking capacity (I m) 500(In=2540A) 630(In=63A)<br> Short-circuit current Inc= I c 10000A<br> SCPD fuse 10000<br> Break time under I n 0.1s<br> Rated impulse withstand voltage(1.5/50) Uimp 4000V<br> Dielectric test voltage at .Freq. for 1min 2.5kV<br> Electrical life 2,000 Cycles<br> Mechanical life 4,000 Cycles<br> Installation<br> Contact position indicator Yes<br> Protection degree IP20<br> temperature(with daily average35) -5~+40<br> Storage temperature -25~+70<br> Terminal connection type Cable/Pin-type busbar/U-type busbar<br> Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity. of power supply and voltage, and free from external interference, voltage fluctuation EKL1-63B single- RCCB with two current paths; two- RCCB; three- RCCB; three- RCCB with four current paths, four- RCCB Current Circuit Breaker<br> Package Contents:<br> 1 x Circuit breaker<br> Only the above package content, other are not included.<br> Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
