Current Sense Transformers datasheet and documents for 855-5101/250-001
Current Sense Transformers Overview
The WAGO 855-5101/250-001 is a split-core current transformer designed for non-invasive current sensing. It features a primary rated current of 250 A and a secondary rated current of 1 A. The device operates within a frequency range of 50 Hz to 60 Hz and has a rated power of 0.5 VA. It supports chassis mounting and is suitable for applications requiring retrofitting without interrupting the current path.
Current Sense Transformers Feature Summary
- Split-core design enables installation around existing conductors without disconnecting the circuit.
- Non-invasive sensing capability allows for safe monitoring of high-current paths.
- Compact form factor facilitates integration into existing electrical systems.
Current Sense Transformers Applications
- Retrofitting existing electrical distribution systems
- Current monitoring in industrial control panels
- Energy management systems requiring non-invasive measurement
Current Sense Transformers Procurement Notes
Verify that the required secondary current matches the system input, as this model provides 1 A output. Confirm the operating frequency aligns with the application's power line frequency (50 Hz or 60 Hz). Ensure the mounting environment accommodates the chassis mount style and physical dimensions specified in the official datasheet.
Current Sense Transformers Selection Notes
Select this component when non-invasive measurement of currents up to 250 A is required. It is appropriate for retrofit scenarios where breaking the primary circuit is not feasible. Consider the 0.5 VA burden rating to ensure compatibility with downstream metering or protection devices.
Current Sense Transformers Part Context
This part belongs to the WAGO 855 series of compact split-core current transformers. These devices are engineered for ease of installation on DIN rails or via chassis mounting, providing a reliable solution for modernizing electrical infrastructure while maintaining safety and accuracy standards.
Current Sense Transformers Replacement Considerations
