3L30

Overview

The Astrodyne TDI 3L30 is a three-phase delta power line filter designed for industrial applications. It supports a rated current of 30 A and operates at voltages up to 440 VAC with a frequency range of 50 Hz or 60 Hz. The unit utilizes a single-stage filtering architecture to manage electromagnetic interference. Key electrical specifications include a maximum leakage current of 1.8 mA, ensuring safety compliance in sensitive environments.

Feature Summary

• Provides effective attenuation of conducted electromagnetic interference in three-phase delta configurations
• Features a low-profile chassis mount design suitable for space-constrained industrial enclosures
• Utilizes quick connect termination style for simplified integration into existing power systems

Applications

• Industrial motor drives and variable frequency drive systems
• Three-phase power distribution units requiring EMI suppression
• Medical imaging equipment with strict EMC requirements
• Automated manufacturing machinery control panels

Procurement Notes

Verify the specific suffix (e.g., L) against the datasheet to confirm terminal type and voltage rating. Confirm that the application voltage does not exceed the 440 VAC limit. Ensure the mounting hardware matches the chassis mount specification. Check for regional compliance certifications such as UL or CSA if required by local regulations before finalizing the order.

Selection Notes

Select this model when a single-stage solution is sufficient for the noise environment. Compare the 30 A current rating against peak load requirements to prevent saturation. Consider the physical dimensions for enclosure fitment. Evaluate whether the delta configuration aligns with the system topology. Review leakage current limits if human contact protection is critical.

Part Context

This component belongs to the Astrodyne TDI L Series, which focuses on low-profile power line filters. The series is engineered for high-performance EMI/EMC suppression in compact form factors. It complements other models in the lineup by offering specialized solutions for three-phase delta networks where space and weight are limiting factors.

Replacement Considerations
