Procurement Notes
Verify the specific part number NBH-20-221-D against official Cosel datasheets to confirm compatibility with your system's voltage and current requirements. Ensure that the chassis mounting style aligns with your enclosure design. Cross-reference technical specifications directly with the manufacturer's documentation to avoid discrepancies in electrical ratings or physical dimensions.
Selection Notes
Select this model when a two-stage EMI filter is required for single-phase applications handling up to 20 A at 250 V. Consider the chassis mount form factor if panel integration is necessary. Evaluate the need for dual AC/DC voltage rating support before finalizing the component choice for your specific power line environment.
Part Context
This component belongs to the NBH series of power line filters from Cosel. The series offers various current and inductance options tailored for different noise suppression needs. The NBH-20-221-D specifically addresses higher current demands within the single-phase category, providing robust performance for demanding industrial environments.
Replacement Considerations
Consult Cosel's official substitution guide for compatible alternatives within the NBH series. Verify that any substitute maintains the same 20 A rating, 250 VAC/VDC specification, and two-stage topology to ensure equivalent EMC performance.
