Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ESC-03-681-D exist with different mounting options like DIN rail. Confirm that the required mounting style matches the exact part number suffix to ensure mechanical compatibility. Check RoHS compliance status and certification requirements against project specifications before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component for applications requiring single-phase filtering at 3 A. Ensure the operating environment stays within the -40°C to 85°C range. Verify that the chassis mounting method aligns with the enclosure design. Compare against DIN rail variants if space constraints differ. Confirm voltage ratings match the system supply.

Power Line Filter Modules Part Context

This model belongs to the ESC series of power line filters from Cosel USA, Inc. The series offers various current ratings and mounting configurations. The ESC-03-681 specifically denotes the 3 A variant with standard terminal block connections. It is distinct from higher current models in the same family.

Power Line Filter Modules Replacement Considerations
