855-4101/500-000

Current Sense Transformers Overview

The WAGO 855-4101/500-000 is a split-core current transformer designed for electrical measurement applications. It features a primary rated current of 500 A and a secondary rated current of 1 A. The device operates with a rated power of 0.2 VA and maintains an accuracy class of 0.5 according to standard IEC specifications. This component supports frequencies ranging from 50 Hz to 60 Hz, ensuring compatibility with standard AC power systems.

Current Sense Transformers Feature Summary

• Split-core design facilitates installation around existing conductors without disconnecting the circuit.
• Compact form factor allows for efficient integration into retrofitting projects.
• Chassis mount configuration provides stable mechanical positioning within control panels.

Current Sense Transformers Applications

• Retrofitting existing electrical distribution systems
• Current sensing in industrial control panels
• Energy monitoring and metering installations

Current Sense Transformers Procurement Notes

Verify that the specific part number matches the required primary current rating of 500 A and secondary output of 1 A. Confirm that the accuracy class 0.5 meets the precision requirements of the target measurement system. Ensure the operating frequency range of 50 Hz to 60 Hz aligns with the local power grid standards before finalizing procurement orders.

Current Sense Transformers Selection Notes

Select this model when non-invasive installation around a conductor carrying up to 500 A is necessary. The split-core architecture is preferred over solid-core types for maintenance-heavy environments where circuit interruption is undesirable. Consider the chassis mount requirement for fixed panel installations rather than DIN rail mounting alternatives.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 Series, which specializes in compact current transformers for industrial interfaces. The series focuses on providing reliable measurement solutions for modern electrical infrastructure. The 855-4101 variant specifically addresses high-current applications requiring precise secondary signal generation for downstream instrumentation.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 500 A primary rating, 1 A secondary output, and split-core topology. Verify that any alternative component adheres to the same 0.2 VA rated power and 0.5 accuracy class to maintain system calibration integrity during replacement procedures.
