3E80 H

Overview

The Astrodyne TDI 3E80 H is a three-phase (Wye) EMC/EMI line filter designed for high-current applications. It supports a rated current of 80 A at 250 VAC with an operating frequency of 50 Hz or 60 Hz. The component utilizes a two-stage filtering architecture to ensure effective noise suppression. Physical termination is achieved via threaded posts sized 5/16-18, facilitating secure mechanical and electrical connections. The unit complies with UL, CSA, LR, and TUV standards.

Feature Summary

• Two-stage filtering architecture for enhanced electromagnetic interference suppression
• Threaded post termination design for robust mechanical mounting
• Compliance with major international safety and regulatory standards

Applications

• Industrial power distribution systems requiring three-phase filtering
• Switch mode power supply input stages in heavy machinery
• Medical equipment power conditioning units

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to confirm terminal configuration and compliance certifications. Ensure the application voltage does not exceed the 250 VAC rating. Confirm that the required current capacity aligns with the 80 A specification under actual operating thermal conditions.

Selection Notes

Select this model when a three-phase Wye configuration is required for high-current loads up to 80 A. The threaded post interface is suitable for chassis mounting where bolt-down stability is critical. Consider the two-stage design if higher attenuation performance is needed compared to single-stage alternatives within the same series.

Part Context

This component belongs to the 3E Series of switch mode EMI filters from Astrodyne TDI. The series provides various current ratings and phase configurations for industrial power conditioning. The 3E80 H specifically addresses the needs of applications demanding significant current handling capabilities with reliable noise filtration.

Replacement Considerations

Consult official substitution guides for equivalent current ratings and phase configurations. Verify that any alternative part matches the 5/16-18 threaded post termination and 250 VAC rating to ensure physical and electrical compatibility.
