LRTU-01Low Voltage Intelligent Power Distribution Monitoring Device

Product Introduction:

The LRTU-01 Low Voltage Intelligent Power Distribution Monitoring Device (originally LRTU for tie cabinet monitoring) is installed on 0.4KV low voltage tie cabinets. It performs real-time measurement of electrical parameters such as busbar voltage and phase on both sides of the tie cabinet, detects various statuses on the tie cabinet, and enables remote opening and closing of the circuit breaker on the tie cabinet.
