Schneider Electric A9Z64240 Residual Current Circuit Breaker Type B-SI, 2P, 40A, 300mA

Residual current circuit breaker Acti 9 iID, sensitive to all types of current, 2-pole, rated current 40A, Type B-SI, nominal fault current 300mA, operating voltage (Ue) 230 AC, 50Hz, insulation voltage 250V AC. Low-wear contact switching mechanism. Mechanical front-side failure indicators (VisiTrip) to show fault current releases. Safe contact indication (VisiSafe) ensures no voltage is present on the output side when the indicator is green. Test button for regular functional checks. Double connection terminals for the bidirectional connection of cables or busbars. Easy removal of the individual device with a busbar installed thanks to the front-accessible mounting element. Additional modular auxiliary devices (optional), such as undervoltage trip (iMN), overvoltage trip (iMSU), shunt trip (iMX), auxiliary status switch (iOF), fault signal switch (iSD). Type B-SI integrates SI technology offering increased resistance against electrical disturbances. Provides protection against smooth DC fault currents in single or three-phase power supply networks caused by frequency converters, inverters & emergency power supplies. Color RAL 9003. Complies with the following standards IEC/EN 61008-2-1, IEC/EN 62423, IEC 61543, VDE 0664.
