NB3LEU Residual Current Operated Circuit Breaker with Over-current Protection(Electronic)

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

    Detailed information, please refer to Certificates Table on the last page.
