37028

Overview

The Simpson Electric 37028 is a three-phase AC current transformer designed for industrial applications. It features a non-invasive solid core construction with a turns ratio of 150:5, supporting input currents up to 150A. The device operates within a frequency range of 50Hz to 400Hz and provides an accuracy of ±1% at 60Hz. Rated at 4VA burden, it utilizes 0.6kV insulation class and is intended for panel or chassis mounting.

Feature Summary

• Non-invasive solid core design for safe current monitoring
• Three-phase AC measurement capability
• High accuracy performance at standard frequencies

Applications

• Industrial power distribution monitoring
• Electrical panel integration
• Current sensing in control systems

Procurement Notes

Verify the specific datasheet version from authorized distributors to confirm compliance with local safety standards. Ensure the installation environment matches the 0.6kV insulation rating. Confirm that the required burden VA does not exceed the 4VA specification to maintain the stated accuracy levels during operation.

Selection Notes

Select this component when a non-invasive solution for three-phase current monitoring is required. The 150:5 ratio suits applications involving higher primary currents. Consider the 50-400Hz frequency range to ensure compatibility with the system's operating frequency. Verify physical dimensions against available panel space before procurement.

Part Context

This part belongs to the Simpson Electric current sense transformer series. It serves as a specialized instrument for measuring alternating current without breaking the circuit. The product line focuses on providing reliable isolation and accurate signal transformation for industrial electrical testing and monitoring equipment.

Replacement Considerations

Direct substitutes must match the 150:5 ratio, 50-400Hz frequency range, and 0.6kV insulation class. Verify that alternative models support three-phase configurations and maintain similar accuracy specifications. Physical mounting constraints should also be evaluated to ensure interchangeability.
