855-3001/250-001

Current Sense Transformers Overview

The WAGO 855-3001/250-001 is a split-core current transformer designed for DIN rail or chassis mounting. It features a primary rated current of 250 A and a secondary rated current of 1 A. The unit has a rated power of 0.2 VA and an accuracy class of 1. It operates within a frequency range of 50 Hz to 60 Hz. The device includes a 3-meter cable length for connection. Physical dimensions include a width of 60 mm, depth of 52 mm, and height of approximately 50.40 mm. It weighs 230 g and complies with RoHS standards.

Current Sense Transformers Feature Summary

• Split-core design allows installation without disconnecting the primary conductor
• Provides isolated signal transformation for monitoring applications
• Includes integrated 3-meter output cable for direct connectivity

Current Sense Transformers Applications

• Electrical energy metering systems
• Industrial process control monitoring
• Power distribution panel instrumentation

Current Sense Transformers Procurement Notes

Verify that the required primary current rating matches the application load of 250 A. Confirm that the secondary circuit accepts a 1 A input signal. Ensure the connected measuring device supports a burden of at least 0.2 VA. Check physical space constraints against the specified dimensions. Validate environmental temperature ranges against operational requirements.

Current Sense Transformers Selection Notes

Choose this model when non-intrusive installation on existing busbars is necessary. Select based on the specific 250 A primary current requirement. Consider the fixed 1 A secondary output compatibility with downstream meters. Evaluate the need for the pre-attached 3-meter cable versus custom wiring solutions.

Current Sense Transformers Part Context

This component belongs to the WAGO 855 series of current transformers. The series offers various primary current ratings and mounting options. This specific part number denotes the 250 A variant with chassis or DIN rail compatibility. It serves as a signal conditioning interface between high-current lines and low-current measurement devices.

Current Sense Transformers Replacement Considerations

Direct substitutes include other split-core current transformers with identical 250 A primary and 1 A secondary ratings. Verify mechanical mounting hole patterns and overall envelope dimensions. Ensure the replacement maintains the same accuracy class and rated power specifications.
