855-505/800-1001

Current Sense Transformers Overview

The WAGO 855-505/800-1001 is a plug-in current transformer designed for DIN rail or chassis mounting. It features a primary rated current of 800 A and a secondary rated current of 5 A. The device has a rated power of 10 VA and an accuracy class of 1. It operates within a frequency range of 50 Hz to 60 Hz and supports terminal block termination.

Current Sense Transformers Feature Summary

• Plug-in design allows for easy installation and replacement on standard DIN rails or via chassis mounting.
• Provides electrical isolation between the primary circuit and measurement equipment with a rated power of 10 VA.
• Delivers a standardized 5 A secondary output corresponding to an 800 A primary input for accurate monitoring.

Current Sense Transformers Applications

• Industrial energy metering systems requiring high-current measurement
• Electrical distribution panels for load monitoring
• Power quality analysis in industrial facilities

Current Sense Transformers Procurement Notes

Verify that the required secondary current matches the 5 A specification, as other variants in the series may offer different ratios. Confirm whether the application requires DIN rail or chassis mounting, as the physical interface must align with the control panel design. Ensure the primary conductor size accommodates the 800 A rating without exceeding thermal limits during operation.

Current Sense Transformers Selection Notes

Select this model when an 800 A primary current range is necessary with a 5 A secondary output. The 10 VA burden capacity supports multiple downstream instruments if connected appropriately. Consider the accuracy class 1 rating for applications demanding precise measurement rather than simple indication. Verify compatibility with existing terminal block wiring standards.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of current transformers, which are engineered for industrial automation and power distribution environments. The series offers various primary current ratings to suit different load requirements while maintaining consistent mechanical dimensions and mounting interfaces for system integration flexibility.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers include 855-301/200-501 from Phoenix Contact for parameter-equivalent applications. Ensure the replacement maintains the same primary-to-secondary ratio and mounting style to avoid redesigning the enclosure or wiring harness.
