BR-10R Control is a microprocessor-based automatic recloser control which interfaces with the
pole-mounted automatic recloser installed on the low and medium voltage overhead distribution
networks, providing directional overcurrent element and auto-reclosing functionality. BR-10R is an
integrated device that measures the voltage and current of the distribution line and generates
various information based on these measured values and performs fuctionalities such as fault
detection, line protection, auto reclosing, communication, status monitoring, and control of the
automatic recloser, and etc.
It provides high connectivity and best performance to users.
The BR-10R Control is conntected to the three-phase automatic circuit recloser via control cables
for interfacing with the 3-phase (both ABC and RST sides) voltage and current inputs, automatic
recloser's contact position information (open/closed) and output contacts for mechanical
operation, status input contacts for gas and manual operating handle, etc.
The BR-10R has 2 built-in EIA-232 ports and uses DNP3.0 and IEC 60870-5-101 to communicate
with SCADA system. TCP/UDP over Ethernet could be optional.
In addition, the external indicator could be selectively displayed for battery low, self alram, trip, and
lockout state. It is a high brightness Ø8 LED installed on the bottom side of the enclosure so that
status can be verified from outside.
