subdivided into at least two independent circuits, each of which
should be protected by a residual current circuit breaker.
- Electrical disturbances of external origin (storms) or high loads may
cause high overvoltages that may in turn cause, first of all, damage
to electronic components of the equipment, and the unwanted
tripping of the residual current circuit breaker. Therefore, it is first
necessary to protect electricity users by means of an overvoltage
limiting device (OVR) and then, if necessary, to use residual
current breakers anti-disturbance APR type.
- The higher continuity of service is reached when each of the
users depending on the same earthing system is protected
individually by its own residual current breaker.
- Installation should be carried out professionally and in accordance
with IEC 60364 specific regulations.
Instructions for user
(To be kept available for future users as well)
Installation of this residual current operated circuit breaker
appreciably increases the safety level of the electric installation and
of the people using it.
If the residual current breaker has a high sensitivity (I ∆n ≤ 0.03 A),
additional protection against direct contacts is also supplied.
However, the installation of a residual current operated circuit breaker
does not mean exemption from all the precautions which should be
taken by all using electric power.
