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.
