855-5005/500-001

Current Sense Transformers Overview

The WAGO 855-5005/500-001 is a split-core current transformer designed for cable conversion applications. It features a primary rated current of 500 A and a secondary rated current of 5 A. The device has a rated power of 0.5 VA and an accuracy class of 1. It operates within a frequency range of 50 Hz to 60 Hz and supports chassis mounting.

Current Sense Transformers Feature Summary

• Split-core design facilitates installation around existing conductors without disconnecting the circuit.
• Provides accurate current transformation with Class 1 accuracy for measurement purposes.
• Engineered specifically for cable conversion and amperage measuring applications.

Current Sense Transformers Applications

• Amperage measuring systems
• Cable conversion setups
• Current sensing in electrical distribution panels

Current Sense Transformers Procurement Notes

Verify that the required secondary current matches the 5 A specification, as other variants offer different ratios. Confirm that the load burden does not exceed the 0.5 VA rated power to maintain Class 1 accuracy. Ensure the mounting method aligns with chassis installation requirements rather than DIN rail standards used by other series models.

Current Sense Transformers Selection Notes

Select this model when a 500 A primary current ratio is required for monitoring high-current cables. The split-core architecture is essential for retrofitting or installing sensors on already terminated conductors. Consider the 0.5 VA burden capacity when connecting multiple meters or transducers to ensure signal integrity.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of current transformers. Unlike the 855-301/200-501 which uses DIN rail mounting and 1 A secondary output, this specific part number utilizes chassis mounting and a 5 A secondary output. It is distinct from lower-rated variants like the 300 A or 200 A models in terms of physical size and electrical capacity.

Current Sense Transformers Replacement Considerations

Direct substitutes include other WAGO 855 series split-core transformers with identical 500 A primary and 5 A secondary ratings, such as the 855-5005/300-001 if the primary current requirement allows for adjustment. Verify that any replacement maintains the 0.5 VA rated power and Class 1 accuracy specifications.
