Product Description

Overview and characteristics of circuit breakers
  • Flexible communication
    It supports various communication methods such as RS485 communication and carrier, micro power wireless, etc., supports DL/T 645 protocol, DL/T 698 protocol and MODBUS protocol, and supports functions such as parameter setting, status query, remote control, etc.
  • Status monitoring
    Real time monitoring of switch opening and closing status effectively supports fault isolation and positioning analysis; it can monitor the temperature of incoming and outgoing line joint and provide early warning of wiring fault.
  • High reliability
    The switch has strong anti-interference ability and high reliability.
  • Temperature detection
    It can monitor and measure the temperature inside the inlet and outlet terminals of the switch and the switch body.
