NB3LE RCBO
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.
