Brief:
XB821 user boundary switch controller is a control equipment specially designed for outdoor medium voltage circuit breakers. When inter-phase short circuit and single-phase earth fault occur in users branch, boundary circuit breaker immidiately open and insulate faulty line, so as to recover other branches power supply.
XB811 reclosing controller can help circuit breakers to realize data acquisition and telemetry, current protection, reclosing, faults recording, remote communication, local/remote control operation, and switch state acquisition /output, etc.
