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)
