Low voltage selectivity with ABB circuit-breakers

← Back to document page

the rated current of the circuit-breaker. This is the zone in which the magnetic protection for thermomagnetic releases or protections S, D and I for electronic releases are normally called on to intervene. These current values usually correspond to a fault on the supply circuit. This event is most unlikely than a simple overload.
