Procurement Notes

Verify the specific part number suffix against official Cosel documentation to confirm terminal type and mounting configuration. Ensure the selected variant matches the required voltage rating and current load for the target application. Cross-reference datasheet specifications for physical dimensions and terminal pitch before integration.

Selection Notes

Select this model for applications requiring robust two-stage filtering in single-phase circuits. Confirm compatibility with chassis or DIN rail mounting environments. Verify that the 30 A rating and 250 VAC/VDC limits exceed operational requirements. Check terminal accessibility for spring-loaded push-down connections during assembly planning.

Part Context

This component belongs to the Cosel NBM series of power line filters. It is designed for general-purpose EMI/EMC suppression in single-phase power distribution networks. The series offers various current ratings and leakage current options to suit different regulatory compliance needs.

Replacement Considerations

NBM-30-000-D is a documented variant within the same series. Verify if the '-D' suffix indicates a specific terminal or mounting difference compared to the base NBM-30-000 model before substitution.
