# Chint Residual Current Circuit Breaker 30mA 6kA - NB1L - 2P 40A | DZ

NB1L Residual Current Operated Circuit Breaker with Over-current Protection(Magnetic) 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.
