Power Line Filter Modules Procurement Notes

Verify the specific suffix designation against official Cosel documentation to confirm terminal type and mounting configuration. Ensure the selected variant matches the required circuit voltage and current ratings. Confirm regulatory certifications such as UL or CSA are present on the datasheet for the specific part number before finalizing procurement specifications.

Power Line Filter Modules Selection Notes

Select this model when a compact, single-phase solution is required for chassis or DIN rail environments. The screwless connection style offers advantages in high-vibration applications compared to traditional screw terminals. Evaluate the 3 A current capacity against peak load requirements to ensure adequate safety margins during operation.

Power Line Filter Modules Part Context

This component belongs to the ESP series of power line filters from Cosel. The series is designed for general-purpose EMI suppression in AC and DC power lines. The ESP-03-332-D represents a specific configuration within this family, distinguished by its 3 A rating and 2.2 nF capacitance value for standard noise attenuation.

Power Line Filter Modules Replacement Considerations

Direct substitutes include other models within the Cosel ESP series that share identical 3 A ratings and 250 VAC/VDC specifications. Verify mechanical compatibility, specifically DIN rail footprint and terminal pitch, when considering alternative part numbers from the same manufacturer.
