37030

Overview

The Simpson Electric 37030 is a three-phase AC current transformer designed to step down high alternating current signals for measurement. It provides a standardized secondary output of 5A from a primary input range up to 300A, facilitating safe and accurate monitoring in industrial electrical systems. This component serves as an interface between high-current circuits and low-range ammeters or data acquisition devices.

Feature Summary

• Provides isolation between high-voltage primary circuits and low-voltage measurement instruments
• Delivers a consistent 5A secondary output proportional to the primary current
• Engineered for integration with standard analog panel meters

Applications

• Industrial power distribution monitoring
• Three-phase motor control panels
• Electrical test equipment interfaces

Procurement Notes

Verify the specific primary current rating required for your application, as models may vary by ratio. Confirm compatibility with the intended secondary load impedance to ensure accuracy. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the physical mounting style matches your panel design requirements before ordering.

Selection Notes

Select this model when interfacing three-phase AC systems with standard 5A secondary rated instruments. Consider the accuracy class and burden voltage specifications relative to the connected meter's input impedance. Evaluate the physical dimensions and terminal type to ensure proper installation within the available enclosure space.
