NL210 Residual Current Operated Circuit Breaker without Over-current Protection
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 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.
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.
It ensures instantaneous tripping (without time-delay).
