Procurement Notes

Verify the specific datasheet version and RoHS declaration status before procurement. Confirm that the 440V AC/DC rating and 4A current capacity align with your system requirements. Ensure chassis mounting provisions match your enclosure design. Check for any recent PCN or labeling changes that may affect part identification or compliance documentation.

Selection Notes

Select this model when a three-phase solution is required for low-current applications up to 4A. The chassis-mount form factor suits panel installations where space is constrained. Verify that the delta connection type matches your network topology. Consider thermal management capabilities if operating near the maximum temperature limits specified in the official documentation.

Part Context

This component belongs to the Schaffner EMC Inc. power line filter family, specifically designed for industrial EMC solutions. It complements other chassis-mount filters by offering a compact three-phase option for lower current ratings. The product line emphasizes reliability and compliance with international electromagnetic interference standards for motor drives and power electronics.

Replacement Considerations

Consult official Schaffner cross-reference guides for verified substitutes. Ensure replacement parts maintain identical three-phase, 440V, and 4A specifications. Verify mechanical mounting dimensions and terminal types to ensure physical compatibility without modification.
