Tripping Current Range
|Detectable wave form||Pulsating direct current sensitive||Surge current proof|
Tripping is ensured for sinusoidal AC residual currents pulsed DC residual currents,alternating residual sinusoidal currents up to 1000Hz,pulsating direct residual currents and for smooth direct residual currents,whether applied suddenly or increasing slowly.
They react to AC and pulsating DC fault current which reach 0 or almost 0 within one time period of the mains frequency.
RCCB’s surge capacity.
Not tripping at standardized 8/20 υs surge-current waves acc.to VDE 0432 Part 2 with surge current values of up to 250A.
