855-4105/400-101

Current Sense Transformers Overview

The WAGO 855-4105/400-101 is a split-core current transformer designed for non-invasive measurement of alternating currents. It features a primary rated current of 400 A and a secondary rated current of 5 A, providing a standard 400:5 current ratio. The device operates within a frequency range of 50 Hz to 60 Hz and carries an accuracy class of 1 with a maximum rated power of 1 VA. It includes a 0.5 m long cable terminated with bare ends for connection. The unit supports a feedthrough diameter of 28 mm for the measurement conductor and utilizes chassis mounting for installation.

Current Sense Transformers Feature Summary

Split-core design enables non-invasive installation around existing conductors without circuit interruption
Chassis mount configuration provides secure mechanical attachment for industrial applications
Standardized 400:5 current ratio ensures compatibility with common measurement instrumentation

Current Sense Transformers Applications

Electrical energy monitoring systems
Industrial power distribution panels
Current protection relay circuits

Current Sense Transformers Procurement Notes

Verify that the required primary current rating matches the application load of 400 A. Confirm that the measurement conductor diameter does not exceed the specified 28 mm feedthrough limit. Ensure the connected burden does not exceed the 1 VA rated power to maintain Class 1 accuracy. Check that the operating frequency aligns with the 50 Hz to 60 Hz specification. Validate that the bare wire termination method suits the target control equipment input requirements.

Current Sense Transformers Selection Notes

Select this component when a non-invasive measurement solution is required for high-current AC lines up to 400 A. The split-core architecture allows retrofitting into existing electrical setups without disconnecting conductors. Consider the 28 mm aperture constraint when selecting cables or busbars. The 5 A secondary output is suitable for standard ammeters and data acquisition modules. Verify space availability for chassis mounting and cable routing.
