The unit features screwless terminal connections and is designed for DIN rail mounting. Key electrical specifications include a leakage current of 37.5 uA and a capacitance value of 330 pF. The component complies with UL, CSA, DIN, and ENEC standards.

Power Line Filter Modules Feature Summary

• Single-stage electromagnetic interference suppression for single-phase circuits
• Screwless terminal block design for simplified wiring installation
• DIN rail mounting configuration for standardized panel integration

Power Line Filter Modules Applications

• General purpose industrial equipment noise suppression
• Power supply input filtering for electronic devices
• Control cabinet EMC compliance enhancement

Power Line Filter Modules Procurement Notes

Verify the specific part number ESP-03-331-D against official Cosel datasheets to confirm screwless terminal compatibility and DIN rail mounting requirements. Ensure system voltage does not exceed 250 VAC/VDC and current remains within the 3 A limit. Confirm regulatory compliance needs match UL, CSA, DIN, and ENEC certifications before procurement.

Power Line Filter Modules Selection Notes

Select this model when single-phase EMI filtering is required for low-current applications up to 3 A. The screwless terminals offer faster assembly compared to screw-type alternatives. Verify that DIN rail mounting space is available in the enclosure. Compare leakage current specifications if sensitive medical or precision instrumentation is involved.

Power Line Filter Modules Part Context

This component belongs to the ES series of power line filters from Cosel USA, Inc. The series includes various current ratings and mounting styles. The ESP designation typically indicates DIN rail mounting with screwless terminals, distinguishing it from chassis-mounted variants like the EAP series.

Power Line Filter Modules Replacement Considerations

Direct substitutes may include other single-phase 3 A DIN rail EMI filters with similar capacitance and leakage current values. Verify terminal type compatibility and physical dimensions before substitution.
