855-5101/750-000

Current Sense Transformers Overview

The WAGO 855-5101/750-000 is a split-core current transformer designed for chassis mounting. It features a primary rated current of 750 A and a secondary rated current of 1 A. The device has a rated power of 0.5 VA and an accuracy class of 0.5. Operating at frequencies between 50 Hz and 60 Hz, this component provides non-intrusive current sensing capabilities suitable for retrofitting existing electrical systems without interrupting ongoing processes.

Current Sense Transformers Feature Summary

• Split-core design enables easy installation on existing busbars or cables without disconnecting the circuit.
• Non-intrusive measurement technology allows for accurate current monitoring in live systems.
• Compact chassis-mount construction facilitates integration into control panels and switchgear.

Current Sense Transformers Applications

• Retrofitting energy data acquisition systems in industrial facilities
• Current monitoring in existing electrical distribution boards
• Integration into building management systems for power analysis

Current Sense Transformers Procurement Notes

Verify that the required primary current rating matches the application load of 750 A. Confirm that the secondary circuit burden does not exceed the 0.5 VA rated power to maintain the specified accuracy class. Ensure the physical dimensions of the split-core window accommodate the cable diameter being monitored. Check for compatibility with standard 1 A secondary instrumentation inputs.

Current Sense Transformers Selection Notes

Select this model when a high primary current capacity of 750 A is required in a compact form factor. The split-core architecture is essential for applications where permanent modification of the conductor is not feasible. Consider the 0.5 VA burden limit when designing the secondary wiring loop. This specific part number is optimized for chassis mounting rather than DIN-rail installation.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of split-core current transformers. The series is characterized by its space-saving design and suitability for retrofitting scenarios. Other variants in the family offer different primary current ratings, such as 300 A, but share similar split-core operational principles and mounting styles.

Current Sense Transformers Replacement Considerations

Direct replacements include other WAGO 855 series models with identical 750 A primary ratings, such as 855-5101-750-001 if available. Cross-manufacturer substitutes must match the 750 A primary, 1 A secondary ratio, 0.5 VA burden, and split-core mechanical interface.
