855-4001/200-001

Current Sense Transformers Overview

The WAGO 855-4001/200-001 is a split-core current transformer from the 855 Series. It features a primary rated current of 200 A and a secondary rated current of 1 A. The device has a rated power of 0.2 VA and an accuracy class of 0.5. It includes a 3 m cable length for signal transmission.

Current Sense Transformers Feature Summary

• Split-core design allows for rapid mounting without interrupting the primary cable
• Compact and hinged construction facilitates easy installation in existing systems
• Color-coded connection system ensures secure and correct wiring

Current Sense Transformers Applications

• Retrofitting energy data acquisition in existing electrical installations
• Space-saving AC current measurement applications
• Industrial automation monitoring where primary circuit interruption is not permitted

Current Sense Transformers Procurement Notes

Verify that the required secondary current matches the 1 A specification and confirm the primary load does not exceed 200 A. Ensure the connected burden remains within the 0.2 VA rated power limit to maintain the 0.5 accuracy class. Check that the 3 m cable length meets the distance requirements between the transformer and the measuring instrument. Confirm environmental conditions are suitable for standard industrial operation.

Current Sense Transformers Selection Notes

Select this model when retrofitting existing circuits without breaking the conductor is required. Choose this unit if a 200 A primary range and 1 A secondary output are needed. Consider this component for applications requiring high accuracy class 0.5 performance. Opt for this split-core type over solid-core variants when space constraints or installation accessibility favor a hinged design.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 Series, which specializes in compact current transformers and Rogowski coils. The series is designed for modern energy data acquisition and industrial automation. These devices support efficient monitoring solutions by providing accurate current measurements while maintaining safety standards and ease of integration into existing control systems.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers: 855-4001/150-001 (150 A primary). Verify compatibility with existing metering equipment before substitution.
