Overview
The Astrodyne TDI 3B30DB is a three-phase economical section power line filter designed for chassis mounting with bolt-in termination. It supports a voltage rating of 250 VAC and a current capacity of 30 A at operating frequencies of 50 Hz and 60 Hz. The unit features a low leakage current of 1.4 mA and measures 3.91 inches in length, 3.31 inches in width, and 1.75 inches in height. It weighs approximately 730.8 grams and holds UL, CSA, LR, and TUV compliance certifications.
Feature Summary
- Provides electromagnetic interference suppression for three-phase delta configurations
- Utilizes an economical single-stage filter design for cost-effective noise reduction
- Supports secure chassis installation via bolt-in terminal connections
Applications
- Industrial machinery power conditioning
- Three-phase motor drive systems
- Commercial equipment requiring EMI/EMI filtering
Procurement Notes
Verify the specific termination style required for your application, as datasheets may list both bolt-in and quick-connect variants within the same series. Confirm that the 250 VAC rating aligns with your system's nominal voltage. Ensure chassis mounting provisions accommodate the specified physical dimensions and weight. Check for updated compliance certificates if operating in regulated environments.
Selection Notes
Select this model when a three-phase solution is required for moderate current loads up to 30 A. The economical design suits applications where high attenuation is not the primary constraint compared to cost efficiency. Ensure the bolt-in termination matches available panel hardware. Consider thermal management requirements based on the continuous current rating and ambient operating conditions.
Part Context
This component belongs to the 3B series of power line filters from Astrodyne TDI. The series focuses on providing reliable EMI/RFI suppression for three-phase AC power lines. These filters are engineered for integration into industrial control panels and power distribution units where space and budget constraints coexist with the need for regulatory compliance.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting structures and electrical specifications before considering alternative models from other manufacturers.
