855-5001/250-001

Current Sense Transformers Overview

The WAGO 855-5001/250-001 is a split-core current transformer designed for DIN rail mounting within the 855 series. It features a primary rated current of 250 A and a secondary rated current of 1 A, with a rated power of 0.5 VA. The unit includes a 5-meter cable length for flexible installation. It operates at frequencies between 50 Hz and 60 Hz, maintains an accuracy class of 1, and supports a maximum voltage of 1.2 kV. The device weighs 230 g and complies with RoHS standards.

Current Sense Transformers Feature Summary

• Split-core design allows for non-intrusive installation without interrupting the test lead or primary circuit.
• Integrated 5-meter cable facilitates connection to measurement devices in confined spaces.
• High accuracy class ensures reliable current sensing for industrial monitoring applications.

Current Sense Transformers Applications

• Industrial energy monitoring systems
• Electrical distribution panel measurements
• Current sensing in automation control cabinets

Current Sense Transformers Procurement Notes

Verify that the required primary current rating matches the 250 A specification of this model. Confirm that the secondary load does not exceed the 0.5 VA rated power to maintain accuracy class 1 performance. Ensure the operating environment remains within the specified temperature range. Check that the 1.2 kV insulation rating is sufficient for the application voltage. Validate compatibility with standard DIN rail mounting profiles.

Current Sense Transformers Selection Notes

Select this component when a split-core solution is required to avoid disconnecting existing conductors during installation. Choose this model if the system utilizes a 1 A secondary output interface. Consider the 5-meter cable length for distance requirements between the transformer and the meter. Verify that the 250 A primary capacity aligns with the maximum expected load current.

Current Sense Transformers Part Context

This part belongs to the WAGO 855 series of current transformers, which are engineered for DIN rail integration. The series provides various primary current ratings and secondary configurations to suit different industrial measurement needs. The 855-5001 variant specifically addresses scenarios requiring high primary current handling with a long integrated cable for remote sensing connections.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure the new component matches the 250 A primary rating, 1 A secondary output, and 0.5 VA burden capacity. Verify that the replacement also supports split-core installation and includes comparable cable length specifications.
