120TYT8-1

Overview

The Delta Electronics 120TYT8-1 is a high-performance, single-stage EMI/EMC power line filter designed for three-phase, four-wire systems. It features a star connection configuration and is rated for an AC voltage of 480V at 50/60Hz operation. The unit supports a current capacity of 120A and utilizes chassis mounting with terminal block connections. Key electrical parameters include capacitance values (Cx/Cx1) of 2.0µF and inductance (L) of 0.32mH, alongside Cy of 1.2nF.

Feature Summary

• Provides effective electromagnetic interference suppression for three-phase power lines
• Designed for robust chassis installation using terminal block interfaces
• Engineered for high-current industrial applications up to 120A

Applications

• Industrial machine tools
• Uninterruptible Power Supply (UPS) systems
• Copy machines and office automation equipment

Procurement Notes

Verify the specific suffix or variant against official datasheets, as Delta often uses numerical suffixes to denote mechanical or electrical variations within the TYT series. Confirm that the terminal block interface matches your existing wiring infrastructure. Ensure the 480VAC rating aligns with your system's nominal voltage to prevent insulation breakdown or performance degradation under load.

Selection Notes

Select this component when a single-stage solution is sufficient for your EMC requirements in a three-phase environment. The 120A rating makes it suitable for heavy-duty machinery. Compare the 0.32mH inductance value against your noise spectrum needs; if higher attenuation is required, consider multi-stage alternatives from the same series. Ensure physical dimensions fit the available chassis space.

Part Context

This part belongs to the Delta Electronics TYT series of high-performance three-phase filters. The series includes variants like 16TYT8, 36TYT8, and 100TYT8, differentiated primarily by current ratings and associated passive component values. These filters are standardized for industrial EMC compliance, offering a consistent form factor and mounting style across the product line.

Replacement Considerations

Publicly confirmed substitute part numbers for the 120TYT8-1 are not available in the provided documentation. Users should consult Delta Electronics directly for cross-reference recommendations or verify compatibility with other manufacturers' 120A three-phase filters based on identical electrical specifications.
