NL1 Residual Current Operated Circuit Breaker without Over-current Protection (Magnetic)
1.1 Function
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.
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.
