• Type B RCCBs, moreover ordinary AC, can come across excessive frequency AC and natural DC earth leakage currents Reducing the danger of fire and/or electrocution throug4h computerized disconnection of the electric supply is dependent upon the choice of the proper sort of RCCB Application Example: EV & PV installations, Frequency converters, UPS installations, High-frequency power converters, Building website power supply cabinets Mode ： Electromagnetic Type(wave style of the earth leakage sensed)： B Rated latest In ：25,40,63,80,100A Poles：2P,4P Rated voltage Ue ：2P 240V~,4P 415V~ Insulation voltage Ui ：500V Rated frequency ：50/60Hz Rated residual operation current(I△n) ：30,100,300mA Rated residual making and breaking ability (I△m)：500A(In≤40A),10In(In＞40A) Short-circuit latest Inc= I△c：10,000A Break time below I△n ：≤0 Rated impulse stand up to voltage(1/50) Uimp ： 4000V Dielectric examine voltage at ind for 1min ：2 Electrical lifestyles ： 2,000Cycles Mechanical lifestyles ： 4,000Cycles FunctionControl electrical circuits humans against oblique contacts and additionalprotection against direct contacts installations opposed to fireplace danger because of insulation faults recent circuit breakers are utilized in housing, tertiarysector and industrySelectionDetectable wave formB classTripping is ensured for sinusoidal AC residual currents pulsed DCresidual currents,alternating residual sinusoidal currents up to1000Hz, pulsating direct residual currents and for tender directresidual currents, whether or not applied out of the blue or increasing slowly sensitivity30mA -additional defense opposed to direct touch timeInstantaneous It ensures on the spot tripping (without time- delay)
