37029

Overview

The Simpson Electric 37029 is a three-phase current sense transformer designed for chassis mounting. It operates within a frequency range of 50Hz to 400Hz and utilizes a non-invasive solid core type construction. The device features a current ratio of 200:5 and provides an insulation level of 0.6kV. At 60 Hz, it maintains an accuracy of ±1% with a burden VA rating of 5.0. The unit weighs 1.75lb and employs screw terminal connections for secure electrical interfacing.

Feature Summary

• Three-phase current sensing capability
• Non-invasive solid core design
• Chassis mount configuration

Applications

• Industrial current monitoring
• Electrical panel instrumentation
• Power distribution systems

Procurement Notes

Verify the specific current ratio requirement, as documentation indicates both 50:5 and 200:5 variants exist for this series. Confirm chassis mounting dimensions and screw terminal compatibility with existing panel layouts. Ensure the operating frequency range of 50Hz to 400Hz aligns with the target application's power system specifications before procurement.

Selection Notes

Select this component when three-phase current transformation is required in a compact chassis-mounted form factor. The non-invasive solid core design simplifies installation compared to split-core alternatives. Consider the 200:5 ratio for standard industrial metering applications requiring precise current scaling within the specified frequency band.
