NBH-20-322-D

Overview

The NBH-20-322-D is a single-phase EMC/EMI line filter module manufactured by Cosel USA, Inc. It is designed for DIN rail mounting and supports a continuous current of 20 A with voltage ratings up to 250 VAC/VDC. The unit features a two-stage filtering architecture to suppress electromagnetic interference in power lines.

Feature Summary

• Two-stage EMI/EMC filtering architecture
• DIN rail mounting configuration
• Terminal block connection interface

Applications

• Industrial equipment power input stages
• Commercial machinery noise suppression
• Power distribution units requiring EMI reduction

Procurement Notes

Verify the specific part number against official Cosel datasheets to confirm compatibility with your system's voltage and current requirements. Ensure that the DIN rail mounting style matches your enclosure design. Check for RoHS compliance status if environmental regulations apply to your deployment. Confirm terminal block specifications match your wiring gauge.

Selection Notes

Select this component when a two-stage filtering solution is required for single-phase AC or DC lines up to 250V. Consider the 20A current rating to ensure it meets the load demands without derating issues. Evaluate the physical dimensions for DIN rail space availability. Compare attenuation characteristics against other single-stage filters if higher performance is needed.

Part Context

This model belongs to the NBH series of power line filter modules from Cosel. These components are engineered for industrial environments where electromagnetic compatibility is critical. The series offers various current and voltage ratings to suit different power distribution needs across commercial and industrial sectors.

Replacement Considerations

Consult Cosel documentation for direct cross-references. Verify that any substitute maintains the same two-stage topology, 20A rating, and 250VAC/VDC rating. Ensure mechanical compatibility with existing DIN rail mounts and terminal connections.
