C65L RCBO 4P CKYB2- C16-4P

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

B curve (3-5 In) protection and control of the circuits against overloads and short-circuits;protection for peolpe and big length cables in TN and IT systems

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.
