Milesight CT103 (250A) LoRaWAN Smart Current Transformer Sensor - 868Mhz

Milesight CT103 With 250A Current Capacity for applications with larger current flows, providing a broader range of current measurement capabilities.

CT103 is a LoRaWAN® Smart Current Transformer for monitoring the energy and analyzing consumption remotely. CT103 provides multiple current options to suit energy monitoring and support sending threshold alarms. The compact size and clamp design allow it to be installed in any indoor space quickly and safely without de-energizing a facility, simplifying the installation and saving costs. Compliant with a Milesight LoRaWAN® gateway, CT103 can be monitored via webpage or mobile App remotely.

CT103 is widely used for energy monitoring and billing of smart buildings, machine failure detection and prevention, etc.

Features :
