Current Sense Transformers datasheet and documents for 855-3001/075-003
Current Sense Transformers Overview
The WAGO 855-3001/075-003 is a split-core current transformer designed for electrical monitoring applications. It features a primary rated current of 75 A and a secondary rated current of 1 A, providing a transformation ratio of 75:1. The device operates at frequencies between 50 Hz and 60 Hz with a rated power of 0.2 VA. It meets accuracy class 3 standards as defined by standard 4055143950565. The unit utilizes a chassis mount configuration and employs a split-core design to facilitate installation around existing conductors without circuit interruption.
Current Sense Transformers Feature Summary
- Split-core construction enables non-intrusive installation around live busbars or cables
- Provides isolated current sensing for metering and protection systems
- Chassis mount design ensures secure mechanical positioning in control panels
Current Sense Transformers Applications
- Electrical energy metering in industrial distribution panels
- Current monitoring for protective relay circuits
- Power quality analysis in commercial building management systems
Current Sense Transformers Procurement Notes
Verify that the required primary current rating matches the application load of 75 A. Confirm that the secondary burden does not exceed the 0.2 VA rated power to maintain accuracy class 3 performance. Ensure the mounting space accommodates the chassis mount form factor. Check compatibility with the target conductor diameter before ordering.
Current Sense Transformers Selection Notes
Select this model when a split-core solution is required for retrofitting existing installations. Choose based on the 75 A primary rating and 1 A secondary output requirement. Consider the 0.2 VA rated power limit when calculating total secondary circuit burden. Verify that the 50 Hz to 60 Hz frequency range aligns with the system operating conditions.
Current Sense Transformers Part Context
This component belongs to the WAGO 855 Series of split-core current transformers. The series offers various primary current ratings to suit different load requirements. The 855-3001/075-003 specifically addresses medium-current applications requiring reliable isolation and standardized 1 A secondary outputs for integration with common instrumentation.
Current Sense Transformers Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official WAGO catalogs for alternative models within the 855 Series that match specific primary current or accuracy class requirements.
