Intelligent Power Distribution Switch with Metering

Series 6NTMU Intelligent Measurement Switch is a new type of low-voltage switching device that integrates high-precision current sensors, measurement units, and protection units. Adopting the design concept of primary-secondary separation and modularization, its secondary modules support hot-swapping, allowing flexible replacement and convenient maintenance. The switch is applicable to three-phase four-wire, neutral-point directly grounded power distribution networks with AC 50Hz, rated current of 250A (adjustable from 100A to 250A), rated insulation voltage of 1000V, and rated operating voltage of 400V. This switch is equipped with a variety of IoT sensing functions, including dual-mode communication (HPLC + HRF), high-precision AC sampling, power supply topology identification, metering box management, electricity theft early warning, power outage event reporting, line loss analysis and evaluation, power supply quality detection, terminal temperature detection, load identification,…
