855-9150/2000-701 is listed in the Current Sense Transformers range at ChipApex. The manufacturer field lists WAGO Corporation. Its product description is CURR XFMR ROGOWSKI 1000A IN-LINE. Review the specifications below when checking this part for your BOM.
The WAGO 855-9150/2000-701 is a Rogowski coil designed for current measurement with a primary rated current of 1000 A. It provides an output signal of 22.5 mV per kA and features a cable length of 1.5 m. The device includes a feedthrough for measurement conductors up to 70 mm in diameter. It operates within a frequency range of 50 Hz to 60 Hz and offers Class 1 measurement accuracy per EN 61869. The unit supports free-hanging installation and is suitable for retrofitting existing systems without interrupting processes.
Verify the specific primary rated current requirement, as documentation references both 1000 A and 4000 A variants within the same series. Confirm that the 70 mm feedthrough diameter matches the conductor size. Ensure compatibility with the required output signal level of 22.5 mV/kA for your conditioning electronics. Check for any specific mounting hardware requirements not included with the coil itself.
Select this model when high resolution and minimal spatial footprint are priorities. It is appropriate for applications requiring accurate measurement without saturation risks associated with traditional transformers. Consider the 1.5 m cable length for integration ease. Verify that the 50-60 Hz operating range aligns with the system frequency. Ensure the 70 mm aperture accommodates the target conductor.
This component belongs to the WAGO 855 Series, which focuses on space-saving Rogowski coils. The series emphasizes Class 1 accuracy per EN 61869 standards. These devices are engineered for modern production methods to ensure precision. They serve as alternatives to bulkier current transformers in energy monitoring setups.
