3B150D

Overview

The Astrodyne TDI 3B150D is a three-phase delta power line filter designed for chassis mounting. It features a single-stage configuration with bolt-in termination. The unit operates at 50 Hz and 60 Hz with a rated AC voltage of 250 VAC and a current rating of 150 A. Physical dimensions are 8 inches in length, 5 inches in width, and 4.75 inches in height. Leakage current is specified at 2.1 mA.

Feature Summary

• Three-phase delta EMC/EMI filtering architecture
• Chassis mount installation with bolt-in connections
• Single-stage noise attenuation design

Applications

• Industrial power distribution systems
• Electromagnetic compatibility compliance for heavy machinery
• Power conditioning equipment input stages

Procurement Notes

Verify the exact suffix designation (e.g., D vs DH) against the manufacturer datasheet to ensure correct terminal configuration and physical fitment. Confirm RoHS compliance status through official documentation before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure mechanical clearance matches the specified 8x5x4.75 inch footprint during system design.

Selection Notes

Select this component when a high-current 150 A three-phase delta filter is required for 250 VAC applications. The bolt-in termination style suits heavy-duty industrial chassis environments. Verify that the 2.1 mA leakage current meets safety standards for the specific installation site. Compare physical dimensions against available panel space to ensure proper mounting.

Part Context

This model belongs to the 3B series of power line filters from Astrodyne TDI. The series focuses on robust electromagnetic interference suppression for industrial power lines. The 3B150D specifically addresses high-amperage requirements within the delta configuration family.
