NB3LEU RCBO



NB3LEU Residual Current Operated Circuit Breaker with Over-current Protection (Electronic)
1. Rated residual operating current
   I∆n = 30 mA: additional protection in the case of direct contact.
2. Tripping class
   AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.
3. 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.
