Milesight RCT-RJ11 | Split-Core Current Transformer for CTH01 (100-1000A)

The Milesight RCT-RJ11 is a split-core current transformer designed for use with the CTH01 Smart Power Monitor Hub. Its clip-around split core installs over a live conductor without disconnecting wiring, and an RJ11 lead plugs straight into the CTH01. Available in 100 A, 300 A, 500 A and 1000 A ranges with Class 0.5 accuracy, it lets you match each monitored circuit to the right CT for precise current and energy measurement. Key Features Split-Core, Clip-OnInstalls around an existing conductor with no need to disconnect or rewire the circuit. Four Current RangesChoose 100, 300, 500 or 1000 A to match the circuit you are monitoring. Class 0.5 AccuracyAccurate current sensing for dependable power and energy data with the CTH01. Plug-and-Play RJ11Connects directly to the CTH01 current channels via an RJ11 lead.
