3B30 L

Overview

The Astrodyne TDI 3B30 L is a single-stage, three-phase delta power line filter designed for chassis mounting. It supports a rated voltage of 440 VAC and handles up to 30 A current at 50/60 Hz operating frequencies. The unit utilizes quick connect termination types and features low leakage current characteristics. Its compact physical dimensions facilitate integration into space-constrained industrial enclosures while maintaining effective EMI suppression.

Feature Summary

• Single-stage filtering architecture for efficient noise attenuation
• Low profile design suitable for dense panel layouts
• Quick connect termination for simplified assembly

Applications

• Industrial machinery power conditioning
• Three-phase motor drive systems
• Commercial equipment EMC compliance

Procurement Notes

Verify the specific suffix 'L' against official datasheets to confirm the low-profile variant specifications. Ensure the 440 VAC rating aligns with your system's nominal voltage. Confirm that quick connect terminals match your wiring harness requirements before finalizing procurement orders.

Selection Notes

Select this model when a cost-effective, single-stage solution is required for three-phase delta applications. It is appropriate for environments where moderate attenuation suffices and space is limited. Compare against multi-stage alternatives if higher frequency rejection is necessary for sensitive loads.

Part Context

This component belongs to the 3B series of economical section filters from Astrodyne TDI. The series focuses on providing essential EMI protection for industrial power lines without excessive bulk or cost, serving as a standard compliance element in general-purpose electrical distribution panels.

Replacement Considerations

Direct substitutes within the same series may include variants with different current ratings or terminal styles. Verify compatibility with existing mounting hardware and terminal connections when considering alternative part numbers from the manufacturer.
