3B100B LF

Overview

The Astrodyne TDI 3B100B LF is a three-phase delta configuration EMC/EMI power line filter designed for industrial applications. It supports a continuous current rating of 100 A at 440 VAC and operates on 50/60 Hz mains frequencies. The unit features a single-stage filtering architecture with chassis mount installation and quick connect or bolt-in termination styles. Key electrical specifications include a leakage current of 1.4 mA to 3.1 mA depending on variant documentation, ensuring compliance with safety standards while maintaining low profile dimensions suitable for panel integration.

Feature Summary

• Three-phase delta configuration for effective noise suppression in industrial power systems
• Single-stage filtering design optimized for high-current applications up to 100 A
• Low-profile flange construction facilitating compact chassis mounting solutions

Applications

• Industrial machinery power conditioning
• Manufacturing equipment EMC mitigation
• High-current distribution panels requiring EMI reduction

Procurement Notes

Verify the specific termination style (quick connect vs. bolt-in) and leakage current rating against your system requirements before ordering. Confirm RoHS compliance status and check regional availability as supply may be restricted. Ensure the voltage rating matches your 440 VAC operational environment. Cross-reference datasheet revisions to confirm dimensional accuracy for enclosure design.

Selection Notes

Select this model when a single-stage solution is sufficient for your noise attenuation needs. Consider the physical dimensions and mounting hardware compatibility with existing chassis structures. Evaluate if the 100 A current capacity aligns with peak load requirements. Compare leakage current limits against sensitive equipment specifications to ensure safe operation within regulatory bounds.

Part Context

This component belongs to the Astrodyne TDI 3B Series, which offers economical section filters for three-phase applications. The series emphasizes low-profile designs for space-constrained installations. It serves as a dedicated EMC/EMI mitigation solution for heavy-duty industrial power lines, distinct from multi-stage or single-phase alternatives in the manufacturer's portfolio.
