The Weidmüller 1481990000 is a split-core current transformer designed for precise measurement of load current consumption using RMS value methods. It features a primary current rating of 400 A and a secondary current rating of 1 A, with an accuracy class suitable for industrial applications. The device operates at 50 Hz and has a burden rating of 5 VA. Constructed as a free-hanging in-line unit, it allows for non-intrusive installation around conductors without disconnecting the main circuit.
Verify that the specific order code KCMA-32-400-1A-5VA-1 matches the required primary and secondary current ratings. Confirm compatibility with the operating frequency and burden requirements of the connected measuring instrument. Ensure the split-core aperture size accommodates the target conductor diameter for proper magnetic coupling.
Select this component when non-invasive current measurement is required for loads up to 400 A. Consider the 1 A secondary output standard for compatibility with common industrial meters. Evaluate the physical dimensions of the split core against available space constraints within the installation environment.
This part belongs to the KCMA series of current transformers from Weidmüller. These devices are engineered for industrial environments requiring reliable current sensing. The model number encodes key specifications including the primary current, secondary output, and burden capacity.
