Overview
The Astrodyne TDI 3B8 is a three-phase delta power line filter designed for chassis mounting. It features an economical section filter configuration with single-stage filtering capability. The component is rated for 440V AC and supports a current capacity of 8A. It utilizes bolt-in termination for secure electrical connections. The unit operates at standard frequencies of 50Hz and 60Hz. Compliance certifications include UL, CSA, LR, and TUV standards.
Feature Summary
- Provides electromagnetic interference suppression through single-stage filtering architecture
- Engineered for three-phase delta circuit configurations
- Facilitates robust mechanical attachment via bolt-in termination method
Applications
- Industrial machinery power conditioning
- Three-phase equipment noise reduction
- Electrical panel integration
Procurement Notes
Verify the specific voltage rating against application requirements, as sources indicate both 250VAC and 440VAC variants within the 3B series. Confirm the current rating matches the load profile. Ensure chassis mounting provisions align with the bolt-in termination style. Check for required compliance certifications such as UL or TUV before finalizing procurement decisions.
Selection Notes
Select this component when a compact, economical solution for three-phase delta systems is required. The 8A rating suits moderate current applications. Verify compatibility with 440VAC systems if higher voltage operation is needed. Consider the chassis mount form factor for space-constrained enclosures requiring bolt-in stability.
Part Context
The 3B8 belongs to the 3B series of power line filters from Astrodyne TDI. This series focuses on economical sections for three-phase applications. The component serves as a passive EMI suppression device. It integrates into power distribution networks to mitigate conducted emissions.
Replacement Considerations
Cross-reference with other 3B series models for similar current ratings. Verify that substitute parts maintain the same delta configuration and bolt-in termination style. Ensure replacement units meet identical voltage and frequency specifications.
