I. Product Highlights
Enhanced shielding layer, resisting external magnetic field interference; IP68 protection, suitable for outdoor scenarios.
Directly connects to our own guide rails/panel instruments, no external integrator required.
Outer diameter Φ8, soft and lightweight, various installation methods (copper busbar bracket, three-axis bracket, cable tie fixing).

II. Core Advantages
Excellent linearity, wide measuring range, resistance to large overloads, no risk of secondary side open circuit, zero power consumption, small positional error, strong long-term stability, and resistance to interference from adjacent current-carrying conductors.

III. Application Scenarios
Smart meters, rectified current measurement, power quality analysis, motor overload/short circuit protection, power frequency/medium frequency welding machine monitoring, medium and high voltage switchgear, RTU/PMU devices, secondary side current detection of industrial electric furnaces.
