Summarize:
The current temperature fault online indicator CSM-SL3-I not only has traditional short circuit and ground fault warning function, also has real-time monitoring of the load current and temperature parameters, and has 485 interface, which can connect DTU Data Remote. CSM-SL3-I is the creative design of Distribution network terminals inferred from the digital application and achieve the Grid standard IEC60870-5-101 Statute, with the Master background's good compatibility and docking, it optimizes distribution automation RTU solutions, that will push the intelligent distribution automation.
Features
Δ High-precision color LCD screen displays the current temperature and switch barometer state real-time
Δ Cables temperature, current monitoring, and accident prevention in the first place
Δ High-precision sensors, the accuracy current measurement accuracy meets distribution automation requirements
Δ Fault monitoring with the trip recognition, completely solve the problem of a ground fault misjudgment
Δ Low-power design, to adapt to a variety of power supply
