General
1. Overload protection
2. Short circuit protection
3. Controlling
4. Used in residential building, non-residential building, energy source industry and infrastructure.
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.
