Milesight LoRaWAN AS923/AU915 Smart Current Transformer CT305 With 3 Phase 300A Current Capacity
CT303 is a LoRaWAN Smart Current Transformer for monitoring energy consumption and analyzing usage remotely. CT303 provides multiple current options to suit different energy monitoring applications and supports sending threshold alarms. Its compact size enables quick and safe installation in any indoor space without de-energizing Circuits, thereby simplifying the installation and saving costs. Compliant with Milesight LoRaWAN gateway and Milesight Development Platform solution, CT303 can be conveniently monitored via webpage remotely. CT303 is widely used for energy monitoring in smart buildings, machine failure detection and prevention, etc.

Perfect for smart buildings, smart city deployments or industrial use-cases.
