Function 1. Personnel and fire protection 2. Cable and line protection against overload and short-circuits. Selection 1. I∆n ≤ 30 mA: additional protection in the case of direct contact. 2. I∆n ≤300 mA: preventative fire protection in the case of ground fault currents. 3. AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase. Curve Specifications
