DESCRIPTION

Personnel and fire protection: Cable and line protection against
overload and short-circuits.

Rated residual operating current
Ian ≤30 mA: additional protection in the case of direct
contact.
Ian ≤300 mA: preventative fire protection in the case of ground fault currents.
Tripping class
AC class
Tripping is ensured for sinusoidal,
alternating currents, whether they be quickly applied or slowly increase.
A class
Tripping is ensured for sinusoidal, alternating
residual currents as well as for pulsed DC residual
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.
