Data Sheet

NL210 Residual Current
Operated Circuit Breaker
without over-current protection
1.3 Approvals and certificates
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
Type B
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.
Tripping sensitivity
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 - protection against indirect contacts, as well as fire
hazard.
Tripping time
Instantaneous
It ensures instantaneous tripping (without time-delay).
