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.
