1.2 Selection
Detectable wave form
AC class
Tripping is ensured for slowly increasing sinusoidal AC residual currents.
A class
Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly.
S, G/SI class
Tripping is ensured not only for sinusoidal AC residual currents but also for pulsed DC residual currents whether applied suddenly or increasing slowly. S, G/SI type with filters against spurious tripping caused by harmonics and transient surges.
With the impact of 8/20us surge 3000A, this high immunity
RCCB will still be in stable status.
