• Compact chassis mount construction facilitates integration into existing systems
• High primary current rating supports heavy-duty industrial monitoring

Current Sense Transformers Applications

• Retrofitting existing electrical distribution systems
• Industrial machinery current monitoring
• Power quality analysis equipment

Current Sense Transformers Procurement Notes

Verify the specific suffix codes match the required primary current rating and secondary output specifications. Confirm chassis mounting dimensions align with panel cutouts. Ensure the operating frequency range matches the system requirements. Check for RoHS compliance documentation if environmental regulations apply to the deployment site.

Current Sense Transformers Selection Notes

Select this component when non-invasive measurement is required for high-current AC circuits. The split-core architecture eliminates the need to break the primary conductor during installation. Verify that the burden resistor or connected metering device matches the 1A secondary output specification to maintain accuracy class performance.

Current Sense Transformers Part Context

This part belongs to WAGO's compact split-core current transformer series, which focuses on ease of retrofitting. These transformers are engineered for environments where existing wiring cannot be interrupted. The series provides reliable current sensing for protection and monitoring schemes in low-frequency AC networks.
