The communication type leakage circuit breaker can record and query detailed
data such as the phase sequence that causes the trip, cause and trip time, and has the
function of historical data recording; the communication series product adopts RS-485
communication port and have multiple communication protocols to choose from. It can
establish communication function with intelligent distribution transformer terminal, upper
computer, etc., and achieve remote parameter adjustment, information query and fault
parameter download.
