The CT105 has a \u003cstrong\u003e500 A RMS\u003c\/strong\u003e rated primary current. Its \u003cstrong\u003e36.5 mm conductor opening\u003c\/strong\u003e is suitable for high-current feeders, large motors, chillers and industrial electrical panels where remote current monitoring is required.\u003c\/p\u003e\n\u003cp\u003eCT105 measures RMS current on a conductor at a \u003cstrong\u003e50–60 Hz\u003c\/strong\u003e supply frequency. It uses up to \u003cstrong\u003e3.3 kHz sampling\u003c\/strong\u003e, \u003cstrong\u003e1 mA resolution\u003c\/strong\u003e, and a manufacturer-stated accuracy of \u003cstrong\u003e±1% above 5 Arms\u003c\/strong\u003e and \u003cstrong\u003e±3% at or below 5 Arms\u003c\/strong\u003e. It supports time-based reporting of current and accumulated ampere-hours, threshold and overrange alarms, and optional temperature sensing through a USB-connected NTC probe. A current measurement alone does not establish accurate true-kWh metering without the appropriate voltage\/power information.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBattery-free operation:\u003c\/strong\u003e the transformer normally harvests power from the measured conductor. For low-load applications or USB operation, it can instead be powered at \u003cstrong\u003e5 V via USB Type-C\u003c\/strong\u003e. With current-harvested power, the official CT10x datasheet lists CT105 minimum reporting current of approximately \u003cstrong\u003e5 Arms at 1-minute intervals\u003c\/strong\u003e and \u003cstrong\u003e4.7 Arms at 10-minute intervals\u003c\/strong\u003e. For lower currents, USB power may be required.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eCT105-868M\u003c\/strong\u003e model is the \u003cstrong\u003e868 MHz \/ EU868 LoRaWAN®\u003c\/strong\u003e regional variant. It supports OTAA\/ABP Class A, an external SMA antenna, configuration by USB Type-C or LoRaWAN downlink, and Firmware Update Over the Air (FUOTA). Standard LoRaWAN gateways and the Milesight Development Platform can provide remote visibility of monitored current and alerts. The design uses a CT clamp and separate wireless transceiver that can be positioned for better RF coverage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical highlights:\u003c\/strong\u003e 500 Arms rated primary current; 150 mArms rated secondary current; 36.5 mm conductor opening; CT clamp dimensions 68 × 86 × 41.8 mm; transceiver dimensions 38 × 34.5 × 16 mm; blue PBT+PC UL94 V-0 housing; IP30 indoor protection; operating range −20°C to +70°C; listed CE, FCC and UL508 approvals. Installation and commissioning should be performed by appropriately qualified electrical personnel under site safety procedures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e CT105-868M. \u003cstrong\u003eSKU:\u003c\/strong\u003e 2ESE2148. \u003cstrong\u003eOEM:\u003c\/strong\u003e Milesight. \u003cstrong\u003eSeller Warranty:\u003c\/strong\u003e 1 year. \u003cstrong\u003eImportant for India:\u003c\/strong\u003e EU868 is not the same as IN865.
