NL1-63 2P 40A 30mA 10KA TYPE A

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.
Tripping sensitivity
10mA – precision instrument leakage protection and bathroom use.
30mA – additional protection against direct contact.
100mA – co-ordinated with the earth system according to the
formula IΔn ＜ 50/R, to provide protection against indirect contacts;
300mA/500mA – protection against indirect contacts, as well as fire
hazard.
Tripping time
Instantaneous
It ensures instantaneous tripping (without time-delay).
Short time delay
It ensures any tripping at least 10ms.
Selective
It ensures total discrimination with a nonselective RCD placed
downstream.
