1.1 Function protection of circuits against short-circuit currents,protection of circuits against overload currents,switch,isolation. NB1 circuit-breakers are used in domestic installation, as well as in commercial and industry electrical distribution systems. 1.2 Selection Technical data of the network at the point considered:short-circuit current at the circuit-breaker installation point, which must always be less than the breaking capacity of this device,network normal voltage. Tripping curves: B curve (3-5In) protection for people and big length cables in TN and IT systems. C curve (5-10In) protection for resistive and inductive loads with low inrushcurrent. D curve(10-14In) protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps). 1.3 Approvals and certificates Detailed information, please refer to Certificates Table on the last page.

1.1 Selection Rated residual operating current I∆n = 30 mA: additional protection in the case of direct contact. Tripping class AC class – Tripping is ensured for sinusoidal, alternating 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. 1.2 Approvals and certificates CATALOG NB3LEU Residual Current Operated Circuit Breaker with Over-current Protection PDF
