1.General 

1.1 Application 

Personnel and fire protection 

Cable and line protection against overload and short circuits 

1.2 General rules for choosing RCBO: 

a.Rated residual operating current 

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 

b.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. 

c.Tripping curve 

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. 

D curve (10-14 In) protection and control of the circuits against overloads and short-circuits;protection for resistive which supply loads with high inrush current at the circuit closing(LV/LV transformers,breakdown lamps).
