NBH-20-101-D

Overview

The NBH-20-101-D is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It supports an AC voltage rating of 250 VAC and a DC voltage rating of 250 VDC with a continuous current capacity of 20 A. The unit features a two-stage filtering configuration designed for common mode noise suppression across the 10 kHz to 10 MHz frequency range. It utilizes a DIN rail mounting style with screw termination type for secure electrical connections. The component operates within a temperature range of -40°C to +85°C and includes a maximum leakage current specification of 12.5 µA.

Feature Summary

• Two-stage EMI/EMC filtering architecture for enhanced noise attenuation
• DIN rail compatible mechanical design for standardized panel integration
• Low leakage current performance ensuring safety compliance
• Screw terminal interface for robust electrical connectivity

Applications

• Industrial control systems requiring DIN rail mounting
• Power supply input stages for noise suppression
• Equipment sensitive to electromagnetic interference in commercial environments

Procurement Notes

Verify the specific suffix 'D' confirms DIN rail mounting style, as other variants may differ. Confirm the manufacturer part number matches exactly to ensure correct leakage current and voltage ratings. Check for RoHS compliance status if required by project specifications. Ensure the operating temperature range meets environmental requirements.

Selection Notes

Select this model when DIN rail installation is preferred over chassis mounting. Compare against NBH-20-102 which offers chassis mount instead. Verify that the 20 A current rating aligns with load requirements. Consider the 12.5 µA leakage current limit for sensitive applications. Ensure the two-stage design provides sufficient attenuation for the specific noise profile.

Part Context

This component belongs to the NBH series of power line filters from Cosel USA, Inc. The series includes various configurations such as chassis mount (NBH-20-102) and different current ratings like the NBH-16 series. The NBH-20-101-D specifically denotes the 20 A variant with DIN rail compatibility, distinguishing it from general purpose or higher current models in the broader product family.

Replacement Considerations

The NBH-20-102 serves as a functional alternative if chassis mounting is acceptable instead of DIN rail. The NBH-20-000-D is another DIN rail option within the same series. Verify that substitute parts maintain identical voltage, current, and leakage current specifications.
