SCT-1250-250

Current Sensors Overview

The Magnelab SCT-1250-250 is a split-core AC current transformer designed for sensing alternating current. It features a rated input of 250 Amps and provides an output of 0.333 Volts at rated current, establishing a specific transformation ratio. The device exhibits linearity accuracy of ±1% within an accuracy range spanning from 10% to 130% of the rated current. Constructed with interleaved core joints for precision, it includes shrouded core blades to protect during installation and ensures no exposed metal parts are present on the exterior surface.

Current Sensors Feature Summary

• Snap closing and opening mechanism facilitates rapid installation without disconnecting conductors
• Shrouded core blades provide physical protection for the core components during the installation process
• Interleaved core joints ensure high measurement accuracy by maintaining magnetic circuit integrity

Current Sensors Applications

• Electrical system energy monitoring
• Power quality analysis in industrial settings
• Current measurement for protective relaying systems

Current Sensors Procurement Notes

Verify that the required primary current rating matches the 250 Amp specification exactly. Confirm the secondary output voltage requirement aligns with the 0.333 Volt standard. Ensure the application environment does not require exposed metal parts, as this unit is designed with a fully enclosed non-conductive exterior. Check compatibility with the connected metering or data acquisition input impedance.

Current Sensors Selection Notes

Select this model when a split-core design is necessary for retrofitting existing busbars or cables without power interruption. The 250 Amp rating suits moderate load applications. The 0.333 Volt output is compatible with standard analog inputs. Consider the ±1% accuracy if precise billing or detailed power analysis is required. Evaluate the snap-action feature against manual clamp requirements for installation speed.

Current Sensors Part Context

This component belongs to the Magnelab SCT-1250 series of split-core current sensors. The series generally covers AC current sensing from 50 to 600 Amps. The SCT-1250-250 specifically denotes the 250 Amp variant within this family, sharing common design traits like the snap-close mechanism and shrouded cores found across the broader product line.

Current Sensors Replacement Considerations

Direct substitutes must match the 250A primary rating and 0.333V secondary output. Verify physical dimensions for aperture size compatibility. Cross-reference accuracy specifications (±1%) and operating temperature ranges. Ensure the replacement also offers a split-core design for similar installation constraints.
