Current Sensors datasheet and documents for SCT-1250-300
Current Sensors Overview
The Magnelab SCT-1250-300 is a split-core current transformer designed for measuring alternating current. It features a split core design that allows installation without disconnecting the primary conductor. The device supports AC current sensing in the range of 50 to 600 Amps, with a specific rating of 300 Amps as indicated by the model suffix. It provides an isolated output signal proportional to the primary current.
Current Sensors Feature Summary
- Split-core construction enables non-intrusive installation around existing busbars or cables
- Designed for accurate sensing of alternating current within specified high-amperage ranges
- Provides galvanic isolation between the primary conductor and secondary measurement circuit
Current Sensors Applications
- Power monitoring systems requiring non-invasive current measurement
- Energy management meters for commercial or industrial electrical panels
- Protective relay circuits for high-current AC distribution networks
Current Sensors Procurement Notes
Verify the specific current rating and burden requirements against the application load. Confirm that the split-core aperture matches the diameter of the primary conductor. Ensure the frequency range aligns with the system operating frequency. Check for compliance with relevant safety standards for the intended environment.
Current Sensors Selection Notes
Select this component when non-invasive installation is required for high-current AC applications. Consider the physical size of the split core relative to the available space in the electrical panel. Evaluate the accuracy class and phase shift characteristics if precise power quality analysis is needed. Ensure the insulation voltage rating meets the system's maximum line-to-line voltage.
Current Sensors Part Context
This part belongs to the SCT series of split-core current transformers from Magnelab. These devices are commonly used in conjunction with power analyzers and data acquisition systems. The series offers various current ratings to accommodate different load profiles in industrial and commercial settings.
Current Sensors Replacement Considerations
Direct substitutes may include other split-core current transformers with matching 300A ratings and compatible output signals. Verify mechanical dimensions and mounting style to ensure fit. Cross-reference electrical specifications such as turns ratio and burden capability.
