3. Main Function
â— Combined short-circuit
and leakage protection into one product overcurrent
â— Digital display the
value of three-phase currents(Optional), voltage,
leakage current and the maximum phase
â— Adjust the overload
protection value as the capacity of distribution transformer or the
actual load (Optional)
â— Automatically display
the cause of cascading trip-out, fault phase and current
â— Will send alerts once
exceed the limit of leakage current, but not trip out when turn on
the warning function
â— Query-able for all
previous tripping time(Optional),
reasons.
â— An intelligent
tracking for line situation, or set operation value as
period(Optional)
â— Standard communication
interface be builted-in for the automatic system of the power
network
â— Be able to identify
and separate surge leakage current(Optional)
