Control electric circuits.
Protect people against indirect contacts and additional
protection against direct contacts.
Protect installations against fire hazard due to insulation faults.
Residual current circuit breakers are used in housing, tertiary
sector and industry.
Detectable wave form
Tripping is ensured for slowly increasing sinusoidal AC
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 Class type with filters against
spurious tripping caused by harmonics and transient surges.
With the impact of 8/20us surge 300A, this high immunity
RCCB will still be in stable status.
