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
