855-5105/500-001 is listed in the Current Sense Transformers range at ChipApex. The manufacturer field lists WAGO Corporation. Its product description is CURR SENSE XFMR 500A CHAS MNT. Review the specifications below when checking this part for your BOM.
The WAGO 855-5105/500-001 is a split-core current transformer designed for non-invasive current measurement. It features a primary rated current of 500 A and a secondary rated current of 5 A. The device operates within a frequency range of 50 Hz to 60 Hz and carries an accuracy class of 1. With a rated power of 0.5 VA, it supports precise monitoring in electrical systems. The unit utilizes chassis mounting for secure installation.
Verify that the required primary current matches the 500 A specification and that the secondary output aligns with 5 A input requirements of the connected metering device. Confirm the operating frequency range of 50 Hz to 60 Hz is compatible with the local power grid standards. Ensure the chassis mounting method suits the available enclosure space and mechanical constraints of the installation site.
Select this component when non-invasive measurement is necessary to avoid circuit interruption during installation. The 0.5 VA burden rating must be compatible with the connected load impedance. Consider the physical aperture size relative to the conductor diameter to ensure proper closure of the split core. Verify that the accuracy class meets the specific measurement precision requirements of the application.
This model belongs to the WAGO 855 series of compact split-core current transformers. The series is engineered specifically for retrofitting scenarios where invasive wiring modifications are impractical or prohibited. These units provide a reliable interface between high-current primary circuits and low-current secondary measurement devices.
No public confirmed substitute part numbers are available.
