1.1 Certificates: CCC,CE,CB,TUV; 1.2 Standard: IEC/EN 60947-2 ,RoHS; 1.3 Rated voltage up to 1000V, Rated current up to 63A; 1.4 Protection of circuits against overload currents; 1.5 Protection of circuits against short-circuit currents; 1.6 NB1-63 DC circuit-breakers are used incommunication systems and PV DC systems.
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.

1.1 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.
Overload protection, short circuit protection and isolation. It is widely used in building power distribution, industrial power distribution, as well as control and protection for a variety of equipment with operating current not exceeding 125A. CATALOGUE: NXB-63 Miniature circuit breaker PDF
