XB864 permanent magnet controller is designed for medium voltage outdoor
monostable, double-wire permanent magnet circuit breaker, the reclosing control
equipment design. Implement permanent magnetic switch of the remote sensing data
acquisition and current protection, reclosing, fault wave record, remote
communication, remote control, local remote control operation, local button
operation, switch state acquisition, switch state output liquid crystal display
(LCD), digital keys, it is more convenient to use
