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.
