C45L-63 Residual current circuit breaker 1 Pole
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).
