855-9150/2000-1251

Current Sense Transformers Overview

The WAGO 855-9150/2000-1251 is a Rogowski coil current sensor with a primary rated current of 4000 A. It operates within a frequency range of 50 Hz to 60 Hz and features a cable length of 1.5 m. The device supports an ambient temperature range from -40 °C to 80 °C. It provides a measurement accuracy class of 1 per EN 61869, ensuring high-resolution data acquisition without saturation effects.

Current Sense Transformers Feature Summary

• Utilizes a non-magnetic split core design for easy retrofitting into existing systems without interrupting ongoing processes.
• Eliminates saturation effects to maintain accuracy across a wide primary current range.
• Offers space-saving dimensions while delivering Class 1 measurement accuracy as defined by EN 61869.

Current Sense Transformers Applications

• Retrofitting energy data acquisition in existing industrial systems
• High-current measurement applications requiring saturation-free performance
• Integration with WAGO signal conditioners such as item 857-552

Current Sense Transformers Procurement Notes

Verify the specific part number suffix against official WAGO documentation to ensure correct specifications. Confirm compatibility with connected signal conditioning modules like the 857-552. Check ambient temperature ratings for installation environments exceeding standard limits. Ensure the split-core mechanism aligns with the conductor diameter of the target application.

Current Sense Transformers Selection Notes

Select this model when a 4000 A primary rated current is required for AC measurements at 50/60 Hz. Consider the 1.5 m cable length for routing constraints. Choose this Rogowski coil over traditional transformers if saturation avoidance and easy retrofitting are critical priorities. Verify that the system supports the output signal requirements for integration with compatible WAGO interfaces.
