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). 1.3 Approvals and certificates CE, KEMA 1.4 Add-on devices AX-5 auxiliary contacts TC-1 terminal cover CATALOG NL210 Residual Current Operated Circuit Breaker without Over-current Protection PDF

1.1 Function Personnel and fire protection: Cable and line protection against overload and short-circuits. 1.2 Selection Rated residual operating current I∆n ≤30 mA: additional protection in the case of direct contact. I∆n ≤300 mA: preventative fire protection in the case of ground fault currents. Tripping class AC class Tripping is ensured for sinusoidal,alternating currents, whether they be quickly applied or slowly increase. A class Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly applied or slowly increase. Tripping curve B curve (3-5 In) protection and control of the circuits against overloads and short-circuits; protection for people and big length cables in TN and IT systems. C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current. 1.3 Approvals and certificates Detailed information, please refer to Certificates Table on the last page.
