Selection

Here are some items for your reference when selecting the device

The earthing systems(TNS,TNC)Short-circuit of the specific power system, which must always be less than the breaking capacity of this deviceThe rated voltage Tripping curves:

B curve (3-5In) ---- protection for people and big length cables in TN and IT systems (lights or socket circuits etc.)

C curve (5-10In) ---- protection for resistant and inductive loads with low inrush current (groups of bulbs, motors etc)

D curve (10-14In) ---- protection for circuits with high inrush current (transformers, double-pole motors, motors with heavy start etc)
