1.1 Function
Personnel and fire protection
Cable and line protection against overload and
short-circuits.
1.2 Selection
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.
AC class – Tripping is ensured for sinusoidal,
alternating currents, whether they be quickly applied
or slowly increase.
