NBM-10-331

Overview

The Cosel NBM-10-331 is a single-phase EMC/EMI power line filter module rated for 10 A current and 250 VAC/VDC. It features a two-stage filtering design with 330 pF capacitance to suppress electromagnetic interference. The unit utilizes chassis mount installation and employs terminal block connections for secure wiring. Designed for robust performance in industrial environments, it ensures compliance with emission standards while maintaining low leakage characteristics suitable for sensitive electronic equipment.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Chassis mount configuration for stable mechanical integration
• Terminal block interface for reliable electrical connectivity

Applications

• Industrial control systems requiring EMI suppression
• Medical equipment power input stages
• Precision measurement instrumentation

Procurement Notes

Verify the specific suffix designation when ordering. The base model NBM-10-331 typically denotes chassis mounting, whereas variants like NBM-10-331-D indicate DIN rail compatibility. Confirm the exact mounting style and terminal type required for your enclosure design before purchase to ensure mechanical fit and correct wiring interface specifications.

Selection Notes

Select this component based on the 10 A current rating and 250 VAC/VDC voltage limits. Ensure the application requires chassis mounting rather than DIN rail options. Verify that the 330 pF capacitance value aligns with leakage current constraints for the connected load. Compare against the NBM-20 series if higher current capacity is needed.

Part Context

This part belongs to the Cosel NB series of power line filters. The series offers various current ratings from 6 A to 20 A. The middle digit indicates the amperage rating, distinguishing it from higher-capacity models like the NBM-20 or lower-capacity units within the same family.

Replacement Considerations

Direct substitutes include other Cosel NBM series modules with identical 10 A ratings. Check for equivalent capacitance values and mounting styles. Cross-reference with manufacturer datasheets to confirm pinout and dimensional compatibility before replacing existing units.
